By "cc" I assume that you mean C++?  The problem is, C++ does "name
mangling".  That is, stuff is added to function names to encode information
about the number and types of parameters.  Your C libraries will, obviously,
not have this.  If you want to link a C compiled function with a C++ program
you need to do something like this:

extern "C"
{
int foo( int, int );
};

Virtually any book on C++ (and probably the DJGPP faq) will explain this
further.
