Sure? I'm not enough of a fool to say yes to a question like that. I 
just know it hasn't been needed before, and it seems unlikely it will be 
needed later on either, gcc micro-version updates tend to be conservative.

My only interest here was to fix the version comparisons in a way that 
makes gcc 5 naturally supported, and I dont really give a damn whether 
there's a micro-version involved or not :) If you feel strongly about 
it, send a patch. I'm not going to object.
