libgomp: Don't include limits.h instead of hidden visibility block
sem.h is included in between # pragma GCC visibility push(hidden) and # pragma GCC visibility pop and includes limits.h there, which since the introduction of sysconf declaration in recent glibcs in there causes trouble. libgomp assumes it is compiled by gcc, so we don't really need to include limits.h there and can use -__INT_MAX__ - 1 instead (which clang and icc support too for years). 2021-07-13 Jakub Jelinek <jakub@redhat.com> Florian Weimer <fweimer@redhat.com> * config/linux/sem.h: Don't include limits.h. (SEM_WAIT): Define to -__INT_MAX__ - 1 instead of INT_MIN. * config/linux/affinity.c: Include limits.h.
