Subject:	opendir crashes with -mno-cygwin

The following very simple program segfaults in opendir when compiled with 
-mno-cygwin but runs OK when not compiled with -mno-cygwin. I tried with 
both gcc 2.95.3-1 and gcc 2.95.3-2.

/* File test_dir.c **********************************************************/

#include <stdlib.h>
#include <stdio.h>
#include <dirent.h>

int main (int argc, char *argv[])

{

DIR *dir;
struct dirent *dp;

if (argc<2) {
         printf("test_dir directory\n");
         return 1;
}

dir = opendir(argv[1]);
if (dir==NULL) {
         printf("Error opening directory %s\n", argv[1]);
         return 2;
}

for (dp=readdir(dir); dp!=NULL; dp=readdir(dir)) {
         printf("\t%s\n", dp->d_name);
}

return 0;

}

/****************************************************************************/

When compiled with -mno-cygwin, if the directory given as an argument to 
the program does not exist, opendir returns NULL as it should. If the 
directory does exist, for example ".", opendir segfaults.
