+From: Kevin F. Quinn <kevquinn@gentoo.org>
+
+Taken from gentoo, original description:
+
+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)'.
+
