This causes build failures on linux with clang (a llvm frontend) which sets the __APPLE_CC__ macro, but doesn't provide crt_externs.h

It seems that it would be more appropriate to check for being on MacOS than checking a vendor specific macro.",bug,closed,normal,,core,1.3.0,medium,worksforme,"build, macos, clang",,,,linux
