One problem is that C++ encrypts (mangles) the function entry point to include
information about scope and parameter type (type-safe linking).

You need to define external entries to the library with:

extern "C" {
	int foo();
	int bar();
	// ...
}

This tells cfront not to encrypt those entries (they have C linkage).

As far as the Object file format not being recognized, well, I can't tell you
much about that.
