Description
Not sure whether this is really our problem to fix or just something to be aware of but building an application with the OSX 10.9+ SDK results in an error on the line 7359 in glew.h
typedef ptrdiff_t GLintptrARB;
typedef ptrdiff_t GLsizeiptrARB;
I see:
fatal error: typedef redefinition with different types ('ptrdiff_t' (aka 'int') vs 'intptr_t' (aka 'long')) typedef ptrdiff_t GLintptrARB;
The following patch (which will get released in a new version of GLFW soon I think) fixes it: https://github.com/glfw/glfw/commit/e7c7ebf6658963edbca3945c1732e0116798d8dd

Research direction
Start with glew.h around line 7359 and compare the linked GLFW commit with the version bundled by openFrameworks. Reproduce the build using an OSX 10.9+ SDK, then verify that the header no longer produces the conflicting typedef error.
