Note that many C/C++ compilers rely on the file extension to determine whether it should be processed using C or C++.
I tested this a file with a simple function and with the following extensions on linux 32 bit and looked at the symbols using nm. For "gcc -c" .c unmangled .C mangled .cc mangled For "g++ -c" .c mangled .C mangled .cc mangled I don't have the intel compiler handy, but I think I remember it uses the same binary for C and C++ compilation and relies very much on the file extension.
