[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [41309] trunk/blender: tweak remove_strict_flags so it can be used with gcc's -Wall

[Luke Swanson]

Hi all, I have the same problem on OSX 10.6

Building from trunk fails with:
cc1: error: unrecognized command line option "-Wno-unused-but-set-variable"
