- added "--icc" Premake flag, to disable PCH and set different warning flags - added required headers - changed debug_warn to not generate constant-expression-in-conditional warnings - changed FAM popup-warning into a log message, so it's not so irritating - Atlas: pass around wxGLCanvas instead of wxGLContext, because the context is sometimes just NULL This was SVN commit r4733.
