What's blocking DDMD?

Ok, tried building with LDC and ran into some issues:

At first I tried an older ldmd2 and it error'ed on labels 
followed by closed brackets. Using a newer version fixed this, 
but perhaps magicport could follow labels with {}.

Afterwards I ran into an issue with LDC on x86_64 with 
__va_argsave, so I switched to 32 bit.

Next I ran into symbol conflicts between root.aav._aaLen and 
object._aaLen (resolved by import'ing root.aav : _aaLen)

Afterwards I needed to change optimize.d's shift_optimize second 
argument from:
Expression function(Type, Expression, Expression)
to:
typeof(&Shl)

This is a hack, I think it was getting tripped up on the 
extern(C++).

Next I have an issue with outbuffer.o getting deleted, so I add a 
step to the make file renaming outbuffer.o to routbuffer.o and I 
change the name in the ddmd command to use routbuffer.o instead.

Unfortunately all that was for naught as I couldn't get it to 
link. I tried to rebuild LDC's phobos and druntime for 32 bit but 
the linker still complained that it was incompatible.
