My biggest gripe is this confusing matrix of compiler flags:

       default  -m32     -m32mscoff  -m64
dmd   OMF      OMF      COFF-32     COFF-64
ldc   COFF-64  COFF-32  Error       COFF-64

The same applies to dub's --arch flag.

Currently, the default works out of the box and I don't want to 
change that. I also don't like the idea of changing semantics and 
break code / expectations of users that way. Maybe we can make 
the current flags for dub/the compilers undocumented and define 
new, consistent flags.
