Use -Wno-error=trampolines
Commit Message
On gentoo, at least with gcc 4.9, -Wtrampolines are enabled by default:
tst-execstack-mod.c: In function ‘tryme’:
tst-execstack-mod.c:16:8: error: trampoline generated for nested function ‘callback’ [-Werror=trampolines]
void callback (void) { ok = true; }
^
cc1: all warnings being treated as errors
But of course these testcases require the use of trampolines.
Ok?
