Works on macOS

[ekrich]

I was able to remove the -lgcc* links and it runs on macOS.

% ./a.out
% echo $?
0

Yes - I think that it works on certain MacOS installs but has warnings on certain versions warning about the libunwind metadata (because it has a conflict with the one bundled as well).

Last time I ran it had something like errors like,

libunwind: Unsupported .eh_frame_hdr version

The big problem happens on Linux installs, especially if you inherit libgcc or libunwind when mixing languages like Rust or C++.
