Hi Dick, Jonathan,

as far as I can see fixed is used only in XeTeXswap.h and sfnt.h. Since that
seems to cause a name conflict, I'd say why not drop the typedef for fixed
and replace it everywhere by le_int32.  I would, however, prefer to have
Jonathan's decision on that.

Yes, xdv2pdf requires the Carbon Framework without any non-Mac substitute.
This Mac-only-ness is an aspect of xdv2pdf I rather dislike.

Probably on all Mac platforms, not just Mac64. Correct?

Something has badly gone wrong here. Jonathan ???

If there are fundamental Mac64 problems we could skip building xdv2pdf for
this platform.  If at all possible, the TL build should succeed for both
intel64-mac and power64-mac, and if so it would be natural to add the 64 bit
binaries.
