gmc puts files in /var/tmp, why not /tmp?

[Paul Barnfather <plb clanger9 demon co uk>]

Is there a way to get gmc to put its tempfiles in /tmp?
In particular, uncompressed zipfiles seem to clog up my /var partition.

Also, does gmc ever purge these files? They seem to stick around for
a long time...
