compile ppc on intel

I didn't know you could compile ppc on an intel mac! I had read about rosetta but never thought much of it. Then tonight I figured I would try and see if the ppc version of PB would even do anything. To my surprise, not only was I able to compile/run, I could create the executable.
Maybe this is old news but I thought this was pretty cool. If you know about this already, do you know of any limitations?

I'm relatively sure nobody here was aware of this as there have been a few threads bemoaning the fact that a PPC machine was needed to compile for that platform.
How about a few more details. Did you use Rosetta? That's implied but not entirely clear from your post.

yes, it's possible as the shipped Apple gcc compiles for both ppc and intel. You can even build an universal binary with these 2 execs. Rosetta use is transparent. Please note than the new OS X 10.6 (Lion) will remove all the ppc support on intel mac.

That's the sad thing about Lion. Some people will not only loose some of their apps if they upgrade but even hardware if they only have ppc drivers. I really don't think they need to drop ppc support but I'm sure it's a marketing technique. Anyway, I may hold on to 10.6 a little longer.

Do you mean OS X 10.
7 (Lion) will remove ppc support?

I am currently compiling separate execs for each processor (using PB for Intel & PB for PPC on the same Mac).
Can you please explain how to build a universal binary ?

Thanks Fred, should have looked harder, thought it was something I was missing in PB
