Re this bug report:

Here the problem seems to be that the test suite is not linking C++
programs correctly.  There's a bug report for openplay with similar
symptoms here:

http://lists.apple.com/archives/openplay-development/2003/Nov/msg00005.html

and the diagnosis is that "you're calling cc to do most of the compile
work, but when you get to link phase, this is unwise - because by
default, the cc link will not include c++ stdlibs, which means you get
link problems like" the first failure in the Bison bug report.

BISON_CXX_WORKS is supposed to be set to 'exit 77' if the C++
environment isn't set up correctly.  Perhaps it should be set to 'exit
77' here?  If so, you might investigate why it's set to ':' even
though the test failure indicates that there's some sort of problem
with the C++ environment.
