Hi all,

Does DJGPP somehow support large files?

I'm still working on building the Schily tools.  This is an excerpt
from its "configure" script -- it detects large file support:

  cat > conftest.$ac_ext <<EOF
#line 21399 "configure"
#include "confdefs.h"
#include <stdio.h>
#include <sys/types.h>
int main() {

/*
 * Check that off_t can represent 2**63 - 1 correctly.
 * We can't simply "#define LARGE_OFF_T 9223372036854775807",
 * since some C++ compilers masquerading as C compilers
 * incorrectly reject 9223372036854775807.
 */
#   define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62))
    int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721
            && LARGE_OFF_T % 2147483647 == 1)
               ? 1 : -1];
return !fseeko;
return !ftello;
; return 0; }
EOF
if { { eval echo configure:21419: \"$ac_compile\" ;} 1>&5; { eval
$ac_compile ;} 2>&5; }; then
  rm -rf conftest*
  ac_cv_largefiles=yes
else
