hmm, perhaps I'll hack some little scripts which create a jail/container
for each compiler version and triggers emerge within them.

Well, if there're header bugs, shouldn't they get fixed before these
libs are stabelized ? ;-O

Okay, adds *10 to the test matrix. Still not yet an too complex 
problem (still linear complexity).

Okay, aggreed. I've reworked my rule, now:

"package build systems MUST NOT enable "-Wall -Werror" (unless explicitly 
asked), but developers SHOULD use them for their test builds"
