+Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
+	This trivial patch causes gcc to emit a warning whenever
+	it generates a trampoline.  These are otherwise hard to
+	locate.  It is rigged to default ON - to have it default
+	to OFF remove the text 'Init(1)' from the common.opt
+	patch, leaving just 'Common Var(warn_trampolines)'.
+	Kevin F. Quinn <kevquinn@gentoo.org> 17 Jan 2006
