> R now fails to build for me (when byte-compiling), interestingly only
with ''less'' fancy GCC optimizations enabled. (It did build with LTO and
Graphite loop optimization enabled).
This is ''really'' weird: R ''does'' build if I just in addition enable
LTO... 8)
(My second Sage 5.0.beta10 build with GCC 4.7.0, without LTO and Graphite
loop optimization, just used `-march=native -O3 -g -fno-strict-aliasing`.)
