Hi,

1) emacs -Q
2) M-: (file-exists-p "//.gz") <RET>

On my computer this needs several seconds to come back. The file does
NOT exist.

If i am in cc-mode and a lione starts with "/// " and i press "ctrl-x
ctrl-f" using ffap then this needs over ten seconds to return, cause
emacs tries to determine if there are files named "//.gz" or "//.Z".

That's not an Emacs problem: a file whose name begins with two slashes
or two backslashes is a UNC-style file name, and your Windows computer
looks it up on the network.  That eventually times out, but can take a
lot of time until it does.

I'm closing this bug report.
