Help targeting macOS

[larsbrinkhoff]

I'd like to make a port to macOS, but it's not really viable to do that without access to a macOS machine.

If I could get ssh access to a machine for a month or so, that'd be really helpful.

Building with C target on latest macOS Mojave with official CommandLineTools C toolchain and Clozure CL works fine except a few trivia:

1. macOS deprecated i386 and probably will remove it in the future, so ld would complaint the default -m32, but simply substitute it with -m64 works out without much problem.

2. Clang does not support -fno-unit-at-a-time.

Practically testing with macOS in VirtualBox is preferred.

Thanks for checking. The C target works, but what I'd like to do is writing the target Mach-O file image from Forth, like how the Linux target writes an ELF file and the Windows targets writes a PE file.

I tried to use Virtual Box at some point, but failed the installation. And now I have other priorities.
