source: trunk/dll/eas.c@ 1505

Last change on this file since 1505 was 1498, checked in by Gregg Young, 16 years ago

Changes to get FM2 to compile with the latest watcom 1.9 beta (mostly type casts of CHAR CONSTANT * to CHAR *). Changes to get the environment settings working everywhere again (broken by the change that moved commands to the INI); Added an environment size variable (set to 2048 which was the largest I found hard coded). Still need to find everywhere the environment size is set and use this variable.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
