Hi,
We've seen that it can be useful, for typechecking purposes, to be able
to compile a whole package with a C++ compiler. But some parts, such as
the regex module, are written in C, and too many code changes would be needed
to make them compile in C++ mode.
This module allows to group such modules in automake "convenience libraries"
and compile them with a C compiler, even if $CC is set to a C++ compiler.
So far only "CC=g++" is supported, but that's sufficient since g++ implements
ANSI C++ fairly decently.
Objections?
