directories for temporary files

[Reinhard Kotucha <reinhard dot kotucha at web dot de>]

Hi,
first of all, thanks to everyone involved in cygwin development.

However, there is a bug in /etc/profile.  The variables TMP and TEMP
are set to /tmp but they are absolutely useless.  These variables are
not used by any program.  Thus all programs write temporary files to
/tmp, regardless of the settings TMP or TEMP.

The appropriate variable on Unix is TMPDIR.  It's recognized by
programs on *all* Unix systems.

You can confirm this easily.  Create a directory /tmp/foo and set
TMPDIR=/tmp/foo.  You'll see that all temporary files go to the
specified directory then.  No chance with TMP or TEMP.

Regards,
  Reinhard
