, g++ isn't even
used for building. and "passing in gcc for CXX seems to work fine." Wonder
if that's changed.
It may be that some minimal amount of C++ support was added just to make it easier to link C++-generated objects into a Haskell program, but autoconf took that (perhaps with reason) as meaning do the full C++ testing bit so now you *must* have it around at configure time.
