Well so far I have two solutions to this recursive grep on Windows 98
problem:

1) The patch I submitted earlier here it is again relative to the 1.3.10-1
version of cygwin:

+                     find_file_data.dwFileAttributes)
+                   set_errno (EISDIR);
+               }
+             else
+               {
+                 SetLastError (ERROR_ACCESS_DENIED);
+                 __seterrno ();
+               }
+           }
+         else
+           __seterrno ();
+       }
       goto done;
     }

OR
2) Compile grep with the HAVE_DIR_EACCES_BUG flag enabled.

I've tested these both on Windows 98. I have no idea what these changes
would do to NT/2000 however.

BTW: thanks to Chris Faylor for helping with the cygwin1.dll compile
