   Is it possible to link a C program with a C++ library?  
   The only a priori problem I could see is that the c++ global
   constructors would not be properly inited.  

Yes, that's the main problem.  One way around the problem is to
include a small C++ program that defines "main" and calls another
function, called something like "cmain", passing all the arguments.
Then the C program uses the name "cmain" where it would have used
"main", to define its top-level function.  Then you use CC as the
linker.  This is kludgey, of course, but it's simple and it works.

You probably also want to provide a header file that defines a bunch
of nice, readable names to expand into the mangled names produced
by cfront.
