I am. I nuke the build dir before each build.

Nope.

If a build fails, I get a mail from the cronjob (which contains also the ~200 
last output lines from make). However, since the error message is usually 
buried in thousands of lines of make commands and debug output, I usually 
don't bother to even try to find the error message.

Sure, I understand this - and I certainly like it. I just wanted to point out 
that I'm already doing automated nightly builds, although detecting build 
failures is not the main purpose, but rather a byproduct.

I haven't looked at it, but Jenkins (http://jenkins-ci.org/) is about 
continuous integration (i.e. automated builds to detect build failures or 
regtest failures). It might be overkill for us, but still, there are solutions 
for exactly this task.

Cheers,
Reinhold
