The Mach-O format does not permit gcc to implement the __thread TLS specification, so we must instead emulate it using a single int cell allocated from memory and stored inside of the thread specific data associated with the current pthread. What makes this tricky is git_errno must be a valid lvalue, so we really need to return a pointer to the caller and deference it as part of the git_errno macro. The GCC-specific __attribute__((constructor)) extension is used to ensure the pthread_key_t is allocated before any Git functions are executed in the library, as this is necessary to access our thread specific storage.
