It was an environment variable CPLUS_INCLUDE_PATH=/software6/compilers/gcc/4.8.1/include/c++/4.8.1 that was set before compiling. Removing this variable seems to make xgcc able to find c++config.h and all C99 support is enabled. I'm going to mark this one as resolved invalid. Thanks again for the insights. Maxime
