Thanks.  I have a question about this below.

Hmm... so building with Mach-O support on GNU/Linux and MS-Windows is
not possible at all?  I'm not sure I understand the "BFD does not
support it" part of the error message: shouldn't BFD that is compiled
as part of GDB be configured to support Mach-O when GDB is configured
with --enable-binary-file-formats='coff,xcoff,elf,macho'?  Or what am
I missing?

Thanks.
