crosstool-ng: patches/gcc/4.3.1/110-trampolinewarn.patch@5243d1b432b1

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch

     2 	This trivial patch causes gcc to emit a warning whenever

     3 	it generates a trampoline.  These are otherwise hard to

     4 	locate.  It is rigged to default ON - to have it default

     5 	to OFF remove the text 'Init(1)' from the common.opt

     6 	patch, leaving just 'Common Var(warn_trampolines)'.
