I find this a terrible, terrible idea. An unreliable side effect of an 
unspecified behavior of a non-ANSI C feature. It will break unoptimized 
builds as soon as we add support for DEP, too, because local functions 
require an executable stack. I am at a loss of words to convey how bad 
of an idea this seems to me
