It seems gcc gets better the newer it is.  I was testing on Fedora 12:

[root at grok xorp.ct]# du -m /usr/local/xorp
2	/usr/local/xorp/sbin
1	/usr/local/xorp/share/xorp/templates
1	/usr/local/xorp/share/xorp
1	/usr/local/xorp/share
2	/usr/local/xorp/lib/xorp/sbin
1	/usr/local/xorp/lib/xorp/bin
13	/usr/local/xorp/lib/xorp/lib
16	/usr/local/xorp/lib/xorp
16	/usr/local/xorp/lib
18	/usr/local/xorp

gcc --version

FC8 isn't quite so good:

[greearb at fs2 corporate]$ du -m /usr/local/xorp/
16	/usr/local/xorp/lib/xorp/lib
1	/usr/local/xorp/lib/xorp/bin
3	/usr/local/xorp/lib/xorp/sbin
19	/usr/local/xorp/lib/xorp
19	/usr/local/xorp/lib
1	/usr/local/xorp/share/xorp/templates
1	/usr/local/xorp/share/xorp
1	/usr/local/xorp/share
3	/usr/local/xorp/sbin
22	/usr/local/xorp/

[greearb at fs2 corporate]$ gcc --version

I'm using the 'lf_pkg.bash' script in the root dir of my xorp.ct repo to install
it...it does my stripping, but I don't know if that has anything to do with it
or not.

Also, make sure you 'rm -fr' your /usr/local/xorp before installing in case there
is some old cruft lying around.

Thanks,
Ben
