[distcc] Wrapper for different GCC versions.

[Daniel Beecham]

Hi there everyone.
First post here, so to introduce me, I'm Daniel. :-)

I have three computers, a Gentoo hardened server, a Gentoo desktop and a 
Gentoo laptop. All run core2duo, but i don't want to give the server 
anything unstable, like the gcc 4.3.

Well, anyway, i've compiled gcc 4.3 (called via /usr/bin/gcc-4.3.1), and 
i want everything compiled by the server (for the laptop/desktop) via 
distcc to be of that version. Searching, i've found 
(http://lists.samba.org/archive/distcc/2006q4/003468.html) a previous 
mail by this mailing list where Patrick shows his way of doing it. 
Here's how it looks for me (thank you, Patrick):

sh-3.2# cd /usr/lib/distcc/bin/
sh-3.2# ls -la

sh-3.2# cat wrapper
#!/bin/bash
exec /usr/lib/distcc/bin/g${0:$[-2]}-4.3.1 "$@"

But, trying to compile, it tells me the gcc 4.3-only flag -march=core2 
is a bad value. (as if it's using gcc 3.4.6. Am i doing something wrong?

Thanks.
Daniel.
