Since you were storing the numbers in ints, and printing them as ints, they
_can't_ be bigger than ints!

Perhaps you have previously used a Borland or Microsoft compiler, where ints
are 16 bits, and RAND_MAX is 32767.  I expect that DJGPP has 32 bit ints, so
RAND_MAX will be 2,147,483,647. (or so)

If you want to restrict the numbers to 16 bits, you will have to use short
ints, rather than plain ints.

See the comp.lang.c FAQ (available from ftp://rtfm.mit.edu) for some discussion
on restricting the range of random numbers.
