Windows: cygwin vs. GNAT mingw

["Terry Westley" <westley@yahoo.com>]

Has anyone successfully used Cygwin in a GNAT-compiled program?

It appears that you can successfully link with -lcygwin, but program will crash.

GDB says:
    Program received signal SIGSEGV, Segmentation fault.
    0x61002ac0 in _size_of_stack_reserve__ ()

I suspect that this has something to do with GNAT on Windows using mingw
and you can't build a program  with both cygwin and mingw.

Here's the smallest program that I tested on:

---------------------------------
#include <stdio.h>

int main (argc, argv)
  int argc;
  char **argv;
{
  printf ("hello cygwin\n");
}
---------------------------------

Compile with this command:

gcc -g -o testcygwin testcygwin.c -L C:/cygwin/lib -lcygwin

If I use the gcc that comes with GNAT, it fails as shown above.
If I compile with gcc that comes with cygwin, it works fine.

P.S. I'm resorting to cygwin because I can't find winserve.dll that
is required when linking with -lwinserve of mingw!
