+Subject: [PATCH] Use gnu++11 standard to prevent errors on PPC.
+
+PPC altivec vectorization triggers a bug when compiling with -std=c++11
+because "bool" is redefined in altivec.h.
+
+Acording to a bug report in GCC, "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 let's use gnu++11 standard.
