What about issuing a warning like 

"gcc 3.3.3 is broken because of bug [bugdescription/url].
if you know your build is not affected by this bug do:
touch .gcc333bugfixNNNN but please be aware that you are 
not supported by the mainline kernel development comunity 
if you do"

and implementing the accompanying logic?
