     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)'.
