    I've had many problems running DJGPP under NT.  RHIDE will not work, it always
crashes with error message 'Divide Overflow' during the first screen write.  None
of the compiler programs would run properly until 'LFN=n' was set.  GCC would do
screwy things like write random ASCII characters to the screen.  After 'LFN=n' was
set, everything except RHIDE worked.  But now things appear to compile differently
under NT than they do under Win95.  My friend (who is working at the NT
workstation) wrote a program:
void Noth()
{}

int main()
{
 for(int i=0; i<20000; i++) Noth();
 return 0;
 }

    And, when compiled (using the same batch file) under NT & 95, yeild different
EXE's (the one created under NT was about 1k bigger).  And the NT-compiled exe
crashes on both machines.  He added some lines to open a file, write the value of
'i' to it, and close the file each time through the loop, so we could see when it
crashed.  It seems to crash randomly between the 42nd and 2000th time calling the
function.

    We've tried that, with no effect.  We had to rename all files with longer than
8.3 names to their truncated 8.3 version.
