I have also encountered the font name problem. If you examine the
implementation of the Carbon font pane in my book, you'll find a
workaround.
As for calling conventions, I don't know. Since code in Mach-O
format works on Intel machines, my guess is that things are somehow
made to work. If RS releases support for universal binaries, then I
expect that external functions in code compiled for x86 will need to
follow the x86 conventions, whatever those are.

Thanks Charles, very enlightening, and of course it works great.
The only problem now is that apparently I cannot set text styles
like bold and italic in a CGContext, but I have to use ATSUI and
that is one realm I don't want to visit. Furthermore, there seem to
be some discrepancies between font names in RB and Quartz.
One question: Your book says "But a study of the PowerPC calling
conventions reveals that it is in fact possible to declare and call
such functions."
Does it mean that it probably won't work in a Universal binary on
Intel?
Thanks,

You can't declare a function to return a struct of size greater
than four bytes. Instead you use the following trick -- declare
the function with the return value as the first parameter.
