Probably, but if that's the case MacOS X can be stealthy about it.

There are utilities one can use to make fat binaries as a
post-compilation or post-linking step, but we don't use any of them.
Based on the build logs this would seem to be the way XCode builds
universal binaries.

However our use of bjam takes a different route. On a given call to
gcc I can specify both -arch i386 and -arch ppc, and the object file
that is built will contain the binaries for both. In this case the
linking phase, too, "just works".

Blessings,
Foster
