--- Comment #5 from Paul H. Hargrove <PHHargrove at lbl dot gov> --- The patch in comment #2 allows the build to complete without the need to --disable-libcilkrts. However, I agree with Jakub (comment #3) that use of a glibc internal macros is a poor idea and a configure-time check is prefered. Just because __cpu_set_t_defined exists today doesn't mean it will continue to exist in later glibc revisions.
