I'm writing a game with DJGPP and Allegro, but a few lines are causing
problems:


if ( (sprite[bullet_collision_counter].spr_id == BULLET_HORIZONTAL)
  || (sprite[bullet_collision_counter].spr_id == BULLET_VERTICAL)
  || (game_counter % 2 == 0) )  // doesn't compile with any other value


If I change % 2 to % 3, GCC hangs.



Elsewhere in the program, there are two (perfectly normal) lines which are
required for a small but important purpose. GCC gives a General Protection
Fault if these lines are not commented out...




This is what my environment variables look like:

TMP=C:\WINDOWS\TEMP
TEMP=C:\WINDOWS\TEMP
PROMPT=$p$g
winbootdir=C:\WINDOWS
COMSPEC=C:\WINDOWS\COMMAND.COM
MSINPUT=C:\INTPOINT
DIRCMD=/ogn
DJGPP=C:\TOOLS\DJGPP\DJGPP.ENV
PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\INTPOINT\MOUSE;C:\TOOLS;C:\DOS;C:\TOOLS\NETWORK;C:\PROGRA~1\SDD60;C:\TOOLS\DJGPP\BIN
MIDI=SYNTH:1 MAP:E
SOUND=C:\PROGRA~1\CREATIVE\CTSND
windir=C:\WINDOWS
BLASTER=A220 I5 D1 H5 P330 T6


Here's my AUTOEXEC.BAT:

rem - By Windows 95 Network - C:\WINDOWS\net start
@echo off
SET MSINPUT=C:\INTPOINT
SET DIRCMD=/ogn
SET DJGPP=C:\TOOLS\DJGPP\DJGPP.ENV
PATH  C:\WINDOWS;C:\WINDOWS\COMMAND;C:\INTPOINT\MOUSE;C:\TOOLS;C:\DOS;C:\TOOLS\NETWORK;C:\PROGRA~1\SDD60;C:\TOOLS\DJGPP\BIN
lh C:\WINDOWS\COMMAND\doskey
lh keyb uk,,C:\WINDOWS\COMMAND\keyboard.sys
SET MIDI=SYNTH:1 MAP:E
SET SOUND=C:\PROGRA~1\CREATIVE\CTSND
SET BLASTER=A220 I5 D1 H5 P330 T6 
C:\WINDOWS\DosSetup.exe   (this is for my PowerVR card, btw)



And here's my CONFIG.SYS:

DOS=HIGH,UMB,AUTO
DEVICE=C:\WINDOWS\HIMEM.SYS
DEVICE=C:\WINDOWS\EMM386.EXE RAM D=64
DEVICEHIGH=C:\DOS\TRICD.SYS
Country=044,,C:\WINDOWS\COMMAND\country.sys



I've also got the output from GCC, but not in text format, it's a PCX
screenshot (zipped to 6K). I don't know if this group would object to a
binary (even a small one) being posted, so I haven't included it here.



Btw, I'm a DJGPP novice, so please reply in laymans terms...
