Subject: Bogus errno twiddling by lstat...

Try the following program:

	#include <sys/types.h>
	#include <sys/stat.h>
	#include <errno.h>


	main()
	{
		struct stat     sb;

		errno = 0;
		printf( "lstat(fred) = %d\n", lstat( "fred", &sb));
		perror( "lstat");
	}

If "fred" exists in the current directory, you would expect that errno
would not have been modified, and the output will be:

	lstat(fred) = 0
	lstat: Undefined error: 0

However, what comes out instead is:

	lstat(fred) = 0
	lstat: No such file or directory

Indicating that lstat is diddling errno when it shouldn't be.

8-(.
