For x32, GCC defines both __x86_64__ and __ILP32__ (but not i386).
And the canonical system name is x86_64-pc-linux-gnu.

Size of long and of pointers is the same between i386 and x32.
However, x32 has native 64 bit support, so programs will get access to
64 bit registers for 64 bit types (e.g., long long).

Right, I haven't noticed any problems with the trunk.

Will 24.2 be released from the trunk or from the emacs-24 branch?
