Sorry I didn't follow this thread and exact reason to change.
I see this as a good reason to leave it as .cc

$ cat tryme.cc 
int main(int argc, char *argv[])
{
        return 0;
}
$ make tryme
c++ -O2     -o tryme tryme.cc 
$ rm tryme
$ mv tryme.cc tryme.cpp
$ make tryme
make: don't know how to make tryme. Stop in /home/zvezdan.
$ gmake tryme
g++     tryme.cpp   -o tryme

Obviously only gmake recognizes .cpp as a C++ file on a Unix system.
With older version of gmake on a different Unix machine .cpp has not
been recognized.
