I'll add some hooks for this.

Was there more here that got dropped, or is this one of the bits that
needs filling in?

Should that ABI version number be changed on the trunk?

Should that number have any relation to's libtool_VERSION,
which also tracks the ABI?  (Everyone remember that the "version" in the map
file is just a text string and does not need to be able to be "calculated"
like a libtool version would, or any other version for that matter.  I would
think that "3.1" should be either "3.2" or "5".)

Should a new GLIBCPP_foo inherit the symbols from GLIBCPP_3.1?  I think it's
supposed to work that way, but this breaks new ground for me.
