The `gcc' program determines whether your program is C or C++ by the
extension, so you technically can compile both C and C++ with it. The
trouble occurs when you link: C++ programs usually need to be linked with a
C++ library. The compiler driver can't figure this out itself, since there's
no visible distinction between C and C++ object files, so you have to tell
it by adding `-lstdcxx' and such to the command line. `gxx' is just a
wrapper program that does this for you and calls gcc. It could conceivably
be written as a shell script like this:
