trying out the spiffy new shared lib support, I get this:

_Dmain? wat?
It's declared in druntime and therefore expected to be included:
https://github.com/D-Programming-Language/druntime/blob/master/src/rt/dmain2.d#L348
I think it needs weak linkage or similar. I don't know if it's possible
to do in D, but in C it can be done like this:
https://github.com/D-Programming-Language/druntime/blob/master/src/rt/dylib_fixes.c
Don't know if that is compiled and linked. There probably needs to be a
way to exclude the C main function as well.
