macos: various fixes

* alloca needs to be _alloca * int64_t and uint64_t are also defined in <sys/_types/_int64_t.h> but as long long, not as long, so adjust out <stddef.h> to agree on Darwin * define __APPLE_CC__ so that <TargetConditionals.h> correctly defines various macros like TARGET_OS_MAC and TARGET_CPU_X86_64
