http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45375 --- Comment #73 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2011-04-07 19:59:30 UTC --- Jan, elfhack only fails to build if I use: ac_add_options --enable-optimize=-O3 in my .mozconfig. When I delete the =-O3 part everything builds fine.
