tempnam() creates a readonly file under Windows 2K using Apache 1.3.27, php as CGI. The file permissions are correct but it sets the RO flag, which is not really usefull ;)

Marking this critical as it prevents much anticipated pear on windows release.

Just forgot to mention that I have reproduced this using latest win32 cli.

It is critical in general too, not only for PEAR, afaik, this is the only way to get a safe temp name and seems to be widely used.

I cannot reproduce it with the stable snapshot from 03/4/4 on w2K CLI.
