RIght.  Except we should not try to maintain compatibility between among trunk versions.  If you want to build as of a particular version then use libraries that match that version.

My next set of commits for LONGCARD make this even more critical because the library has hardwired stuff that that makes it require a particular version of the compiler to compile it.  ;-)

Yes.

It very soon will not be.
