Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
yann@1162
     5
	This trivial patch causes gcc to emit a warning whenever
yann@1162
     6
	it generates a trampoline.  These are otherwise hard to
yann@1162
     7
	locate.  It is rigged to default ON - to have it default
yann@1162
     8
	to OFF remove the text 'Init(1)' from the common.opt
yann@1162
     9
	patch, leaving just 'Common Var(warn_trampolines)'.
