# GLEW's headers use <cstdint>, which requires -std=c++11 with
# older versions of GCC.
#
# It's probably quite unsafe to mandate C++11 through GLEW's
# buildlink3 file (in case a dependent package actually requires
# a more recent version), so this remains here as a hack.
#
# mesa-demos is not explicitly using -std=c++XX anyway (it should be).
