osnr / minimal-osx-tcc-hello.c

Created October 27, 2019 07:19

	// should work with tcc 0.9.27 from: https://bellard.org/tcc/ which I
	// think merges minimal Darwin support from https://github.com/andreiw/tinycc
	// (I think only `-run` works; it can't output a Mach-O executable?)
	//
	// but the header and libc situation on macOS for non-GCC/clang is
	// such an incredible mess -- I did kinda get it working, but it's
	// more fun to just write something that calls directly into the OS &
	// has no dependencies (:
	//
