I added the non-AMD 64-bit "versions" to the page at
http://www.prowiki.org/wiki4d/wiki.cgi?DocComments/Version

> # X86_64 (AMD and Intel 64 bit processors)
>     * AMD64 (AMD 64 bit processors)
>     * EM64T (Intel 64-bit extensions)

The new Xeons have this halfway mode that is not Itanium.
And "X86_64" should probably be used here, instead of the
vendor-specific AMD64 version ? (they should be compatible)

For PowerPC®, "PPC" is the 32-bit version and "PPC64" the 64-bit.
In Apple systems, G3 and G4 are 32-bit and the G5 is 64-bit.

I'm not sure what names that the SPARC® family uses, but
I think that "SPARC" is 32-bit and "UltraSPARC" is 64-bit ?


Still think that it could be a good idea to define 32 vs 64
as common versions, like GDC does already. But Walter didn't.
