Thanks, that would explain it.  That was my original point: it would be nice
if something like that, perhaps in a more concise form, to be recorded in
the commit log, so dumbasses like me would not annoy you by their stupid
followup mails.

Unfortunately, you're correct: these little things and nuances are poorly
documented.  I'll try to cook up a patch that talks about USE_GCC proper
usage, unless you (or anyone else) beats me on that. ;-)
