From bd215ef170fb85b7572b617dacdeab26edd3d21c Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sun, 25 Sep 2016 20:28:03 +0200 Subject: always assume tgkill is present We do not support 2.4 Linux kernels anyway, and almost all newer 2.6 kernels should have tgkill syscall. Cleanup the raise situation, pt-raise.c is unused, sync raise.c with latest GNU libc.
