(sorry for the belated response, I was on vacation).

I'm currently leaning towards having the API as a separate source tree
that can be compiled against 4.6 through 4.8 onwards (hiding all
necessary compatibility cruft within it [1]), generating a library that
plugins can link against, providing a consistent C API across all of
these GCC versions.  Keeping it out-of-tree allows plugins to be written
that can work with older versions of gcc, and allows the plugin API to
change more rapidly than the rest of gcc (especially important for these
older gcc releases).  Distributions of gcc could build the plugin api at
the same time as gcc, albeit from a separate tarball.

When the API is more mature, we could merge it inside gcc proper, I
guess.

I'll try to post something later today.
