From e0af4b2c8f8e29ac6f8eccef401c7c004355359d Mon Sep 17 00:00:00 2001 From: Leonardo Sandoval Date: Wed, 1 Jul 2015 12:57:48 +0000 Subject: gcc-target.inc: Remove non-related gcc headers from include_fixed folder Without this patch, the D's include_fixed folder may change after building it (due to the gcc's fixinc.sh script, executed on the do_compile task) and changes depend on the current sysroot headers, making the gcc's builds non-deterministic.
