Re: Call for testing Cygwin snapshot (getopt and -liberty don't mix)

[Peter Rehley <peter at rehley dot net>]

Hi,

I just noticed something else that may or may not be a problem  
(noticed when working on tftpd).  When I link with iberty (-liberty),  
the getopt function doesn't return the correct value for the option  
argument.  Here is a sample program

#include <stdio.h>
#include <getopt.h>

int main (int argc, char *argv[])
  {
  int c;
  while ((c = getopt(argc, argv, "a:b:")) != -1)
    {
    switch (c)
      {
      case 'a':
        printf ("a received with option %s\n",optarg);
        break;

      case 'b':
        printf ("b received with option %s\n",optarg);
        break;
      default:
        printf ("Invalid options\n");
        break;
      }
    }
  return 0;
  }

when I compile with
gcc -o opt_test opt_test.c

and type
./opt_test -a hello -b goodbye

I see
a received with option hello
b received with option goodbye

When I compile with
gcc -o opt_test opt_test.c -liberty

and type
./opt_test -a hello -b goodbye

I see
a received with option (null)
b received with option (null)


I notice this for 1.5.18 and the 20051215 snapshot.  It did work in  
1.3.22.
