I was trying to track down a problem I was having with grep not recursing
subdirectories and this appears to be the problem:
from grep.c in grep-2.5-1:
in the function grepfile (char const *file, struct stats *stats) at
line 911:

      while ((desc = open (file, O_RDONLY)) < 0 && errno == EINTR)
	continue;

      if (desc < 0)
	{
	  int e = errno;

	  if (is_EISDIR (e, file) && directories == RECURSE_DIRECTORIES)
	    {
	      if (stat (file, &stats->stat) != 0)
		{
		  error (0, errno, "%s", file);
		  return 1;
		}

	      return grepdir (file, stats);
	    }

the call to open is leaving a 13 (EACCESS) instead of 21 (EISDIR) in errno
so the call to grepdir doesn't happen.

Platform is Windows 98, cygwin1.dll is version:1.3.10
