After https://github.com/D-Programming-Language/dmd/pull/1732 is pulled RDMD
should be able to the following:

1) Emit an error on missing main if 'entry' is not found. This will avoid
displaying linker error messages.

2) When RDMD supports building libraries (e.g. using the -lib or maybe
--lib/--static switch) it should warn or error if a 'main' function is found.
This will avoid linker errors for multiply defined 'main' symbols when the user
links the built static library with his code at a later point.

3) When RDMD supports building DLLs it should verify there's an entry point and
that the entry point is dllmain.
