This is because the default compiler (gcc 2.95) does not define things
like __SIZEOF_LONG__ and __GNUC__ is not a case in the checks for the
different compilers. It is checked e.g. for the signedness of char. This
fixes this for me. I have not submitted it to the next branch because I
assume this is another Kitware magic upstream tree:
