Hi Iain,

Thanks for the reference.
I'm trying to build from your master-wip-apple-si branch and it doesn't
build too:

The directory that should contain system headers does not exist:
  /usr/include
make[3]: *** [stmp-fixinc] Error 1
rm gcov.pod fsf-funding.pod lto-dump.pod gpl.pod cpp.pod gfdl.pod gcc.pod gcov-dump.pod gcov-tool.pod
make[2]: *** [all-stage1-gcc] Error 2
make[1]: *** [stage1-bubble] Error 2
make: *** [all] Error 2

Thanks,
Roman
