+# "The problem lies within SDL_cpuinfo.h.  It includes altivec.h, which by
+# definition provides an unconditional vector, pixel and bool define in
+# standard-c++ mode.  In GNU-c++ mode this names are only defined
+# 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.
