Hello!
The command 'gcc -v --help' reports that the switch '-m64' can be used to
produce 64-bit output for the x86_64. It also mentions '-mtune=core2'. When I
try to compile GNU Emacs 23.3a (which I'll patch to get the "AppKit Emacs") GCC
4.6.1 fails to build the temacs executable:

The libraries in /opt/opt/lib are 64-bit. The compiled object files in src are
"Mach-O 64-bit object x86_64" according to file and "architecture: x86_64"
according to lipo. The files /usr/lib/crt1.10.5.o, /usr/lib/libSystem.dylib,
/sw/lib/gcc4.6/lib/libgcc_ext.10.5.dylib are also OK, since "fat". But
/sw/lib/gcc4.6/lib/gcc/i386-apple-darwin10.8.0/4.6.1/libgcc.a is faulty, or
unusable and without alternative:
lipo -info /sw/lib/gcc4.6/lib/gcc/i386-apple-darwin10.8.0/4.6.1/libgcc.a
input file
/sw/lib/gcc4.6/lib/gcc/i386-apple-darwin10.8.0/4.6.1/libgcc.a is not a fat file
Non-fat file:
/sw/lib/gcc4.6/lib/gcc/i386-apple-darwin10.8.0/4.6.1/libgcc.a is architecture:
i386
So the package gcc46 is not usable.
There is also the question why /usr/lib/crt1.10.5.o is linked and not
/usr/lib/crt1.10.6.o or why no /sw/lib/gcc4.6/lib/libgcc_ext.10.6.dylib is
built (only /sw/lib/gcc4.6/lib/libgcc_ext.10.[45].dylib exist).
Mac OS X 10.6.8, Xcode 4.0.2 and 3.2.6 (for Tiger and PPC64 support)

Clovis' Consideration of an Atmospheric Anomaly:
The perversity of nature is nowhere better demonstrated than by the
fact that, when exposed to the same atmosphere, bread becomes hard while
crackers become soft
