3-way universal support?

[Michael_google gmail_Gersten]

Will macports ever support a three-way universal, for the following systems:

1. PPC/10.5.8
2. i386/10.5.8
3. x64/10.6.2

Obviously, 10.5.8 systems cannot compile for case #3, but a 10.6.2
system should (in theory) be able to compile for all three cases.

Any likelihood that macports will support this?
