Hi, there.

Looking at the GCC docs and reading the mail archives on DJ's site leaves
me still a bit unclear as to whether DJGPP supports the 64-bit long long
int type.

At the outset, please let me emphasize my recognition that this is _not_
ANSI standard C. In fact, some messages report that it may not be
supported for GCC on the i386 platform, but only on some other
processor(s).

The following program suggests either that indeed this type is not
supported on DJGPP, or that I've goofed <grin>.

#include <stdio.h>
int main(void)
{
  long long int _n0 = 1222333444555LL;
  printf("\n\nNow _n0 = %lli.\n\n",_n0);
  return(0);
}

Interestingly, although I wasn't able to find mention of a printf() 
format specifier for this type, either %lld or %lli (a guess) provokes no
complaints from GCC -- but yields a result suggesting a 32-bit rather than
64-bit variable (-1732234805). 

Out of curiosity, I thought I might check just in case I should be linking
in an extra library or the like.

Most appreciatively,
