I've just been digging for some stuff on a very old backup and came across my list of which version of Lazarus preferred which version of FPC. These were broadly i386 on Linux, but I have no reason to believe that other platforms I tinkered with (SPARC, ARM, MIPS) were different.
I've tacked on a couple of newer entries and post it here in the hope that it might be useful to somebody at some point.

This could possibly go into the Wiki somewhere, but I'm not sure where... possibly at the root of the release docs if there is such a thing.
