Hi all!

Just ran into what looks like a bug in libc. Using 2.01, compile
the following C program:

#include <stdio.h>
int main (int argc, char ** argv)
	{
	int rc;
	char * old, * new;
	extern int errno;

	if (argc != 3)
		{
		printf ("usage: %s old new\n", argv[0]);
		exit (0);
		}

	old  = argv[1];
	new = argv[2];
	rc = rename (old, new);
	printf ("old=%s\nnew=%s\nrc=%d\nerrno=%d\n", old, new, rc, errno);
	}

e.g.:
	gcc tst.c -o tst.exe

and run it under Windoze95: 

	tst foo bar

Run it once with LFN=Y and once with LFN=N, and note that when LFN=Y it
fails with ERRNO 22.

It must be either a bug in _chmod() (which knows about LFN stuff) or
a real Windoze bug, I'm not good enough to determine which! :^(
