Well, I've a (almost trivial) patch that makes it work fine on Intel 
Macs, according to the submitter of the bug. For the next release, I 
intend to fix it in a very conservative way. For this purpose, I need to 
know how to identify an Intel Mac using preprocessor macros. Does anyone 
on this list know which macro is set there? (Hint: on a Linux system, 
that would be "__linux__".)

(I've already tried contacting people, finding it in the gcc sources, 
googling, but was unable to find anything.)

Regards
-richy.
