I personally use the following trick in the `Makefile.am' that actually
links against a C++ library:

  CC = $(CXX)

AFAIK, this is the only portable way to link, eg. a C program against a
C++ library (using `cc -lstdc++' works with GNU C++ but other C++
environments do not necessarily have `libstdc++').  In order to link
against a C++ library without having a C++ compiler, one needs to have
`libstdc++' (or equivalent) statically linked into the C++ library.
