`aout4lb' is used to modify the symbols in a .o file. -- e.g. myfile.o
The modifications are listed in a .4lb file. -- e.g. myfile.4lb
Output is placed in a .olb file. -- e.g. myfile.olb
The .4lb file has 2 types of entry:
rename: _oldsym _newsym
All renames are completed before exports are processed.
Symbols which are exported are given global characteristics,
all other symbols are given local characteristics, comdefs
are moved to bss.
If a library entry is composed of multiple source files, then
the globals which link the source files may be spurious when
the combined files are stored as a library or archive entry. Use
`aout4lb' to clean up the result. In a dynamic linking environment,
global symbol clashes must be avoided. After `aout4lb' has set up
the desired globals, `strip' may be run to eliminate the local
symbols and thus make the library entry smaller.
