running binaries built on Mac OS X 10.4 on Mac OS X 10.5

Hello All,
Can I run binaries built on an x86 Mac OS X 10.4 machine on a 10.5 x86 machine?

I am using gcc

Thanks in advance...

As a general rule, I would expect that to work. There are, of course, subtle changes between the versions, but those should be fairly limited.
