If you remove the stdarg.h file from the
$djdir$/lib/gcc-lib/djgpp/3.21/include directory, you won't get the
compilation errors. There is in fact a stdarg.h file in the $djdir$/include
directory, which gets its va_* from $djdir$/include/sys/djtypes.h, the same
file that $djdir/include/stdio.h gets its va_* from.

Also, it's recommended to make the main function into:
int main (void);
instead of just
main();
