There have been two problems: * GLFW itself was compiled with the definitions for compiling _against_ GLFW (fixed by removing requirement for external glfw) * rglfw.c was being compiled as C code, although it includes Objective C files. This _might_ break the Windows build, needs to be checked. Fixes #391, but as noted I'd prefer though a separate source directory and build script for GLFW.
