Actually,

I'm going to start a cronjob on a local build box that I use. I'll
have it start building list-samples (with CT_LOG_SEE_TOOLS_WARN=y set)
and report on warnings, build success, and build failure. With each
build linking to the build log.

It's really hard to not have build warnings, so don't be afraid of the
number of build warnings. Lower is always better though ;-)

I'll make it update crosstool-ng's local clone between each item in
list-samples, so that if Yann's repository updates, then the build
status will update.

My build box is an quad core 2.4GHz with 4G of memory, I should be
able to do 4 builds at a time or 1 build with 4 jobs. This box runs
debian sid.

I have another "slower?" box that can run fedora 14 builds that is a
dual ht pentium4 3.2GHz with dual-channel 1.5G of memory (yea, I need
to give this box a memory upgrade...). 4 from above would be a little
less then 2 on this box (1.7 builds or 1.7 jobs, 4G of - matched -
memory on this box would probably be 2 builds at a time or 2 jobs).

I'll update again when I find a place to post the build results.
