Unfortunately, I think they have; and I think this is part of their
control games going too far. The in-place upgrade to 10.6 removes all
dev tools from /usr. Fair enough, the os controls /usr, dropping ppc
support is a big change, new Xcode is easily available. But no
warning, no noise on the internets? This goes far beyond dropping
support for deprecated apis.

That's the impression I got from the bug tracker at macports. I think
the macports toolchain has resolved most issues (for native
compilation); and my next efforts were either to use this, or try to
pick up the appropriate patches. If we're going to use the patches,
I'd probably add a POST_PKG_UNPACK or APPLY_LOCAL_PATCHES hook to the
Makefile. Setting configure options in *.mk files is fine, but I'd
prefer to be lazy with larger changes. I'll start another topic before
changing the Makefile though.

Binutils succeeds with ./configure --disable-werror (and make is now
gmake). I'm having trouble downloading GCC, will try again in the next
few days.

Interesting, I hadn't seen mingw-64 before, and it prompted a thought.
I just checked a few binaries, and the OSX toolchain seems to be 64
bit by default. I know you've got Debian x64 working now, but given
the open issues with FreeBSD amd64, I'm guessing there will be more
issues than Apple's changes. Let's make a note in the docs for the
time being.
