No it won't. You can have a C function and C++ function using the same name 
and same arguments. Because C and C++ uses different mangling, the linker 
will see them as two different functions. The only problem comes in if you 
declare them both in the same file and try to use it, the compiler becomes 
confused over which one you want.

extern "C" int _mangled_main(int argc, char **argv);

int _mangled_main(int argc, char **argv)
{
   return 0;
}

That's acceptable C++ code, and will leave the C-style _mangled_main 
undefined.

AFAIK, forcing the user to use a specific main type is unnacceptable. 
Especially since it'd break existing programs.
