I don't understand why this is relevant, would you please
expand on your answer?

I realize that g++ can compile programs when linked with a
library that contains both C++ and C modules.

What I don't understand is why gcc cannot compile standard C
programs when linking with a library that includes both C++ and
C modules.  Why should programmers have to know that a library
contains both C++ and C modules when selecting a compiler for
their application?
