Currently, if user-defined main() function exists, specifying -main switch will
fail to compile.

// test.d
void main() {}

$ dmd -main -run test
test.d(1): Error: only one main/WinMain/DllMain allowed, -main switch added
another main()

But I think this is unnecessary restriction. Compiler can stop adding "another
main" when user-defined main() detected.
