As I mentioned lightly in bug report #265 back on 4/11/98,
I've been attempting to move a small program which is working
fine on a BSD box over to NT. Under both RC3 and RC4 NT binaries,
I find that the fseek call on an opened file does not move
the pointer.  Simple on the fly script follows:

$fp = fopen("some_file", "r");
fseek($fp, 20);
echo "pointer is at " . ftell($fp) . "\n";
fclose($fp);

ftell always reports 0 for me, and subsequent fgetc or fgets
return data from the beginning of the file.

This is only on the NT port.
