/************************************************************************/
/* 5 APR 1987 Portable C Conversion WCC */
/* - Epson init string changed from hex (\x00) to octal (\000). */
/* - Use () with A?(c=B):(c=C) for portability. If it's an error, */
/* it seems to be a very common one. */
/* - Made use of host compiler's strcmp() and strcpy() as they are */
/* usually written in assembly and run faster. */
/* - Globally replaced "alpha_" with "alp_", "alloc_" with */
/* "allo_", and "tmpchr" with "tmpch" to avoid multiply */
/* defined symbol errors on compilers that only support */
/* @$%&*&?>}\~~@# 6-character names. */
/* - Added abs() macro for compilers that don't have one. */
/* - Used some data initialization to kill off some code. */
/* - Made miscellaneous small tweaks for portability. */
/* - Cleaned out old BDS C stuff to improve readability. */
/* - Cleaned up abortion with use of rf_blk.rf_cnt as a pointer */
/* link to the next rf_blk. This construct will NOT work */
/* in environments like the MSDOS large model where ints */
/* are smaller than pointers! */
/* */
/* 9-26-83 Microsoft C 1.04 Conversion WHR */
/* - \t between line numbers and text to fix indenting problem. */
/* - added option -e for output to Epson in condensed print. */
/* - toupper() and isupper() are macros, not functions. */
/* - eliminate side effect in toupper(*++arg) in main(). */
/* - change alloc() to malloc(). */
/* - add #define NAMES that are not in stdio.h */
/* - MS-C requires () in statement A?(c=B):(c=C) error or not?? */
/* */
/* 4-30-83 Computer Innovations C-86 1.31 Conversion WHR */
/* - #include filename changed to allow a disk drive prefix, D: */
/* - convert if(fprintf(...) == ERROR) lst_err(); to fprintf(..); */
/* - convert if(fopen(...) == ERROR) statements to == NULL. */
/* - C86 requires () in statement A?(c=B):(c=C) error or not?? */
/* - remove getc() == ERROR check in fil_chr(). */
/* - convert file conventions from BDS C to C-86. */
/* - comment out BDS unique statements, mark revised statements. */
/* keep all BDS statements to document conversion effort. */

/* Its has the ability to handle nested include files */

/* - Routing of list output to disk */
/* - Cross-referencing of reserved words */
/* - Processing of nested include files */
/* - Generation of listing only */
/* */
/* Usage: xc */
/* */
/* Flags: -i = Enable file inclusion */
/* -l = Generate listing only */
/* -r = Cross-ref reserved words */
/* -o = Write output to named file */
