This is probably because Windows 95's memory security is poor compared to
CWSDPMI (I guess its not really their fault though, because if it _was_ as
good as CWSDPMI, many programs like this would crash and M$ would get the
blame. Ever tried running DUKE3D, or DooM with CWSDPMI already loaded? PAge
faults galore).

Still seems strange. Try creating a brand new file and typing this in, then
compile it. have you deleted your *.o and *.exe files to make sure you re
starting fresh? Reset your computer (maybe something strange is happening
with a disk cache or anything... as soon as Win'95s memory gets breached all
hell breaks loose in the form of mysterious bugs).

I can't see any reason why you would need to. There haven't been any
problems with DJGPP for anyone that can't be fixed :)
