I have the same problem. Also when I use setitimer to call alarm I can't
set it to work more than 10 times in second. In linux 100 times and I
think in all other UNIXes at least same. Gettimeofday working sucks.
And my signal handler gets called only 10 times in second. Is there
anything to do to make it work better? Is it a bug in DJGPP? I think it
should work better and be compatible with UNIXes or at least Linux. Does
usleep also work so, does it only use 1/18 second delays? It works
sometimes strange.
Any comments?
