raise(-1) has stopped returning an error recently

[Duncan Roe]

Hi,

I stumbled across this when running 'make check' in the grep source directory.

test-raise failed when it didn't a few weeks ago. I cut it down to the STC at
the end of this email

Under Linux:
> 16:15:57$ ./test-raise
> raise(-1) returned -1

Under Cygwin:
> 16:16:51$ ./test-raise.exe
> raise(-1) returned 0

Hope this is nothing too complicated,

Cheers ... Duncan.

#include <stdio.h>
#include <signal.h>

int
main (void)
{
  int retcod;

  retcod = raise (-1);
  printf("raise(-1) returned %d\n", retcod);
}
