# context-sensitive by cpp. SDL_cpuinfo.h is included by SDL.h.
# Including altivec.h makes arbitrary code break."
#
# Acording to a bug report in GCC [1]:
# "You need to use -std=g++11 or undefine bool after the include of altivec.h
# as context sensitive keywords is not part of the C++11 standard".
# So use gnu++11 instead of c++11 only for altivec system.
