1.7 +Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
1.8 + This trivial patch causes gcc to emit a warning whenever
1.9 + it generates a trampoline. These are otherwise hard to
1.10 + locate. It is rigged to default ON - to have it default
1.11 + to OFF remove the text 'Init(1)' from the common.opt
1.12 + patch, leaving just 'Common Var(warn_trampolines)'.
