I can get exact info from my MacOS 10.7 machine later, but its gcc is llvm-gcc-4.2 IIRC.
Here are my 10.5 and 10.6:

Paul,

Haven't you been running Intel compilers on OS X?

Also, do we have specifics about which gcc's on Mac OS X?  I have (OS X 10.5.8):

Folks at Oracle should decide, but I suspect "Solaris 10" should be updated to "Solaris 10 and 11", or just "11".
