From: Brian Paul Date: Mon, 23 Feb 2015 20:33:50 +0000 (-0700) Subject: mesa: move math-related function into new c99_math.h file X-Git-Tag: android-x86-6.0-r1~11745 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=cbd287f094b4bd7a6030edf97f5330b4c3fa9a5c;p=android-x86%2Fexternal-mesa.git 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.
