==================

Important notes
---------------

- IMPORTANT: You have to rewrite the initialization code of dynamic
link libraries created with emx: main() has been replaced with
_DLL_InitTerm()

- IMPORTANT: mkdir() now has two arguments. Before linking, change
and recompile all modules that use mkdir()


Highlights
----------

- New versions of GNU programs have been ported: GCC 2.3.3, GDB 4.7

- _DLL_InitTerm(), _CRT_init() and _CRT_term() for dynamic link
libraries

- (Awkward) support for calling 16-bit OS/2 API functions

- Keyboard (Kbd), Mouse (Mou) and Video (Vio) subsystems can now be
used under OS/2

- A simple graphics library has been added (320x200x256 mode only)

- A text-mode video library has been added

- Functions for reading and writing extended attributes have been
added


emx
---

- New system call for __read_kbd(); some but not all _read_kbd() bugs fixed

- New system calls: __sleep2(), __waitpid()

- File name truncation (SET EMXOPT=-t) fixed


emx for OS/2
------------

- emxio.dll: the functions didn't save the EBX register

- fork() fixed: fork() didn't work before a call to malloc()

- FIONREAD also works if ICANON is set for the handle

- _outps8() fixed

- _syserrno() now returns the last error code for the current thread

- If the size of the stack object is 16 KB or smaller, emx.dll creates
a new object for the stack and expands the stack as needed using a
guard page and an exception handler. (emx.dll 0.8e and older always
do this, independently of the size of the stack object.) If the
size of the stack object is greater than 16 KB, the stack is not
changed, that is, the stack object is used for the stack. Programs
that use emx.dll and are linked with LINK386 and need more stack
space than declared in the .EXE file and the stack size declared in
the .EXE file is 16 KB or less, don't work with emx 0.8f and later.
The default stack size (defined by emxomf) is 8 KB. Therefore
programs are unaffected unless they use more stack than declared by
the STACKSIZE statement or the /STACK option of LINK386 or by the
.STACK segment in an OBJ file and that stack size is 16 KB or
smaller. No real programs should be affected. Note that the
(obsolete) Limited Availability release of OS/2 allocates space in
SWAPPER.DAT for all pages of the stack object. Therefore, you
should use a stack size of 16 KB or smaller and the -mprobe option
of GCC if compatibility to the Limited Availability release of OS/2
is essential. If your program uses DosSetPriority and the stack
size is set to 16 KB or smaller, you have to rename DosSetPriority
to DosTrueSetPriority in /emx/lib/os2/dos.imp, assemble
/emx/lib/os2/code1.s, rebuild libos2.a and put code1.o into
libos2.a. This is only required if you re-link your program, it
isn't required for existing executables

- An import library for emxio.dll is now available; _outp8() etc. are
supported when linking with LINK386 or when using emxlibc.dll

- longjmp() now works with user-installed exception handlers


emx for DOS
-----------

- New emx option: -ac (data and stack executable)

- New emx option: -C# (commit memory)

- Bug fixed: -c didn't work

- Access to ports 0 through 0xffff can be enabled by _portaccess().
Previous versions restricted access to ports 0 through 0x3ff

- FIONREAD works for all types of handles

- select() has been implemented

- Additional debugger commands: VP and VX; page table dump changed


emxbind
-------

- TERMGLOBAL and TERMINSTANCE module definition file statements now
supported

- Option for setting the heap size: -h#

- Option for setting the OS/2 stack size: -k#

- The STACKSIZE statement can be used for setting the OS/2 stack size

- By default, a 16 MB stack object for OS/2 is now put into the .EXE
file


emxomf
------

- Convert (I2) import records to (I3) import records

- Convert line number information unless -s is used. This feature
enables limited debugging with IBM's IPMD debugger

- No longer requests emx.lib to be linked


emxomfld
--------

- Call RC to handle .res file

- Bug fixed: LIB environment variable not correctly set

- Use /debug option of LINK386 unless -s or -S are used


touch
-----

- New -c option: don't create files


GCC
---

- #pragma pack implemented for C++

- The -s option is passed to emxomf

- The -mnoprobe option has been renamed -mno-probe

- -mno-probe is now default. If you create threads with
DosCreateThread and don't set bit 1 of the flags argument, you have
to use -mprobe. -mprobe is also required if you want to trap stack
overflow

- GCC now passes libemx1 and libemx2 instead of libemx (and emx.lib)
to the linker

- As emxomfld now knows about .res files, you can use .res files on
the GCC command line even when using -Zomf

- After all the other libraries but before -lemx2, -los2 is passed to
the linker. Therefore, you no longer have to use -los2. Using -los2
(in old makefiles, for instant) doesn't hurt


GDB
---

- `info float' command fixed

- Switch to debuggee session only on CALL instructions

- Redirection supported by `set arg'


GNU ld
------

- The -R option is no longer automatically turned on for import
libraries of type (I1)

- `.o' is appended to the symbol indicating the start of the text
segment of a module unless the symbol starts with `-l' or already
ends with `.o'. This is required to make GDB work with GCC's
MKTEMP_EACH_FILE `feature'


GNU nm
------

- New -d option: don't demangle C++ symbols


Header files and libraries
--------------------------

- Header files adapted for -traditional and C++

- Value of HZ (defined in sys/param.h) fixed

- Prototypes added to curses.h

- New header files: conio.h, sys/utsname.h, sys/wait.h

- S_ISCHR etc. defined in sys/stat.h

- There are now two emx syscall libraries: libemx.a has been replaced
with libemx1.a and libemx2.a, libemx.lib and emx.lib have been
replaced with libemx1.lib and libemx2.lib. libemx1 contains the
syscall interface to emx.dll, libemx2 is the import library for
emx.dll

- New functions: ffs(), uname(), waitpid(), _dt_*(), _ea*(),
_getname(), _inps16(), _inps32(), _int86(), _memdif(), _outps8dac(),
_outps16(), _outps32(), _sleep2(), _splitargs(), _wait*()

- _read_kbd() now available with -Zsys

- The sign of the number returned by _fncmp() is now significant

- pclose() now uses waitpid()

- popen() now parses the command line correctly

- emxlibc.dll now supports 256 file handles and 256 streams

- malloc() and friends in emxlibc.dll are thread-save now

- tempnam() return value fixed; avoid infinite loop for invalid PREFIX

- nls_init() fixed

- frexp() fixed

- popen() improved

- open() and sopen(): errno fixed for O_CREAT

- mkdir(): now sets errno to EEXIST if directory already exists

- scanf(): bugs fixed

- mktime(): the argument is interpreted as local time

- wait(): use errno of system call

- memcmp() return value fixed (sign was wrong)

- strstr (s, "") should return s

- _flush() writes a linefeed immediately in _IOLBF mode

- index(), rindex(), strchr(), strcmp() and strrchr() coded in
assembly language

- Bug fixed: strtol ("0", whatever, 0) didn't work

- printf() no longer prints "-#NAN". "#NAN" is printed instead

- SOM added to libos2


Sample and test programs
------------------------

- New sample programs: eatool, graph, wm_demo and wm_hello

- align.c renamed pack.c


0.8e (13-Sep-1992)
==================

Important notes
---------------

- IMPORTANT: Recompilation of all source files is required due to
changes in the header files and the C library. All .o and .a files
must be recreated from the source

- If the linker complains about `_streams' undefined, you haven't
recompiled all source files

- IMPORTANT: the -s emxbind option has been renamed -i

- When using GNU Emacs 18.58.3 for OS/2 2.0 with emx.dll 0.8e, you
have to replace the string

"/s /c"

with the two strings

"/s" "/c"

in compile.el, shell.el and simple.el. Also replace

"/q /s"

with

"/q" "/s"

and byte-compile compile.el, shell.el and simple.el. Then, run
dump-emacs.cmd.

- When recompiling GNU Emacs 18.58.3 for OS/2 2.0 using emx 0.8e, you
should put the line

(setq completion-ignore-case t)

into the .emacs file as readdir() no longer turns all file names
into lower case

0.8c (19-Mar-1992)
==================

Important notes
---------------

- *** YOU SHOULD RECOMPILE ALL YOUR PROGRAMS *** because the header
files and the library have changed. If you can't recompile a
program (due to lacking sources, for instance), use

emxbind -u \emx\bin\emxl myprog

to update emx in the .exe file

*** DO NOT RE-LINK A PROGRAM WITHOUT RECOMPILING ALL ITS MODULES ***
As several definitions in stdio.h and fcntl.h have been changed,
just linking with the new library without compiling with the new
include files won't work. Really. We apologize for the
inconvenience

---

- The -f# option will be removed for emx 0.8f, better recompile *now*
programs which require -f#

returned if the limit is exceeded

- __spawnve(): if P_DEBUG is used, the child process will be started
in a separate session unless the -E option is used

- __ioctl2(): FIONREAD, TCFLSH, TCSETAF

- __ptrace(): PTRACE_SESSION
