[tlbuild] trial builds for TL'13

[Mojca Miklavec]

Hello,

The sources don't compile with clang on Mac OS X because of a bug in
clang. (The bug has been fixed, but getting the latest clang to users
will take a while.)

This is not particularly important since gcc and llvm-gcc work fine,
but there is one option for a workaround. Modifying
     Work/texk/web2c/xetexd.h
by adding one extra line: inclusion of ApplicationServices.h before
texmfmp.h is loaded:
     #define XETEXCOERCE
   + #include <ApplicationServices/ApplicationServices.h>
     #include "texmfmp.h"
solves the problem. (I'm not sure about the origin of xetexd.h though
and I didn't test the complete compilation yet.) It just makes sure
that xmmintrin.h is included before texmfmph.

Khaled said that he would worry about this once transition away from
Carbon was complete.

I'm not saying that this should necessary be fixed. After all, it's a
compiler bug. But I believe that anyone compiling on Mac should be
aware of this. If nothing else, MacPorts will want to use clang for
compiling XeTeX.
