New submission from Karl Richter:
`./configure` both prints `checking for g++... no` and
WARNING:
By default, distutils will build C++ extension modules with "g++".
If this is not intended, then set CXX on the configure command line.
if `/usr/bin/g++` is present and executable which doesn't seem to be
constructive because it's quite common that one wants to use `/usr/bin/g++` as
CXX compiler if available. In case incompatibilities exists with other C++
compilers there should a check and more detailed error message.
Furthermore the error message doesn't explain if a part of distutils won't be
build because the message sounds like the C++ extension is built, but does it
work without a C++ compiler?
Specifying `CXX` environment variable or `--with-cxx-main=/usr/bin/g++`
`configure` option works fine.
