[Devel] Better Mac patch for gcc

[Dan Williams]

Hi,

Someone will need to run autoconf in builds/unix after this patch but 
before commit as it touches configure.ac and aclocal.m4, and the copy 
of autoconf that ships with OS X is not GNU autoconf, so I didn't 
include the diff of configure in the patch.

Fixes:

a) problem with library versioning in libtool on Darwin/OS X.  This 
might need changing, since we need a good way to specify the 
compatibility version of the dylib, instead of just using 
(major.minor-1.0)

b) Revamps Carbon/pure-Darwin choice (was there any?).  Two choices, at 
./configure time:
./configure    (builds for pure-Darwin, defines DARWIN_NO_CARBON)
./configure --with-old-mac-fonts  (builds for resource-based fonts on 
OS X)

c) including ftmac.c when building as Unix with gcc and 
--with-old-mac-fonts

d) Use two-level namespace on OS X now (and stop using -undefined 
suppress as a result)

Comments on the patch?  It shouldn't break the CodeWarrior build stuff.
