--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Because the eating of comma is a GNU extension. So it is enabled in GNU
compilation modes (the default, for C -std=gnu89, -std=gnu99, -std=gnu11, for
C++ -std=gnu++98, -std=gnu++03, -std=gnu++11, -std=gnu++0x, -std=gnu++1y) but
not in the more strict standard modes (-std=c{89,99,11},
-std=c++{98,03,11,0x,1y}).
