From cbd287f094b4bd7a6030edf97f5330b4c3fa9a5c Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 23 Feb 2015 13:33:50 -0700 Subject: [PATCH] mesa: move math-related function into new c99_math.h file The alternative would be to include math.h in c99_compat.h but that seems heavy-handed. This patch also replaces INLINE with inline in the c99 math function wrappers. Fixes MSVC build.
