Are there any predefined macro constants that I can use in ifdefs to
determine which version of gcc is doing the compiling?
I have some code which needs to compile one way if using gcc 3.1 or later
and another way if using 2.95.

Yes: __GNUC__ and __GNUC_MINOR__
For example, you can use
#if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 95)
to check for gcc 2.95 or later.
