Boyd,
thanks for the hint that Apple released the 5553 sources.
FWIW if you apply the patch from
http://r.research.att.com/gfortran-5531.diff
and add gfortran sources from gcc-4.2.1 (or any later 4.2.x if you
wish)* you will get gfortran for free with full Apple driver support
(the patch is against 5531 but it works with 5553 as well).
Cheers,
Simon
* - you can extract gcc/fortran and libgfortran from the FSF gcc
sources and copy/move it to the Apple's sources - something like:
cd gcc_42-5553
tar fvxj ~/gcc-4.2.3.tar.bz2 gcc-4.2.3/gcc/fortran gcc-4.2.3/libgfortran
mv gcc-4.2.3/gcc/fortran gcc/
mv gcc-4.2.3/libgfortran .
rm -rf gcc-4.2.3

It's a bug in Apple GCC, as near as I can tell.
It might be fixed in the most recent Apple patches to GCC 4.2, which
have been posted at:
http://www.opensource.apple.com/darwinsource/DevToolsMar2008/
gcc_42-5553/
I cobbled up a MacPorts port file that plops these patches on top of
a "mainline" GCC 4.2.1 and builds C,C++, and Objective-C
compilers.It's a horrid hack, but it works, and you don't have to
have an ADC membership to get it, and it works on Tiger, as well as
Leopard.
(I say "might" because I'm not sure.. I'll have to check, as I'm not
at my work machine right now.)
The most recent versions of Apple-GCC-4.2.1 -- released with their
iPhone developer kit -- fix this problem (at least on Intel)... note
that the iPhone is an ARM platform (not Intel or PowerPC), but as a
side-effect of updating the compiler for iPhone platform support,
they fixed the inline-assembly.
Now I'm after them to un-break gfortran after applying their
Objective-C-2.0 patches...
I'm not sure this helps, but I suggest anyone interested in GCC 4.2
on Mac to sign up for their (free) Apple ADC and (free) Apple iPhone
SDK memberships, and download the iPhone SDK.
Best of luck!
