Having /tmp on the root filesystem is a Bad Thing(tm) anyhow (even if
space is not a consideration). However, /tmp and /var/tmp are better
kept separate. The better solution would be one of the following:

1. Use MFS for /tmp (assuming you have no swap space problems).
2. Make /tmp a link into the /usr filesystem.

You may also want to clean up your root filesystem by:
1. Removing old kernels (i.e. kernel.old and kernel.prev if you've ever
upgraded your system).
2. Making sure ~root/ doesn't have any left-overs in it (for example, if
you've ever fired up Netscape as root you're likely to have about 5MB of
Netscape cache on your root filesystem...).
3. Removing core dumps that may end up in the root directory by many
daemonds/utilities (if they ever core-dump).

As for the sources, you can remove anything you want. You just won't be
able to make world then...
