From cc223e1eed69775a323a59628ad93fc79390c2f2 Mon Sep 17 00:00:00 2001 From: Ben Boeckel Date: Tue, 2 Aug 2016 11:31:50 -0400 Subject: Intel-C: declare support for gnu11 Without extensions, functions like `strdup` are not available since they are actually controlled by feature flags such as _SVID_SOURCE and _BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are set, so the functions are not declared properly leading to compile errors. Reported-by: Adam J.
