digitalmars.D - DMD and 64-bit

Am I correct in assuming that DMD generates 32-bit by default and that
for 64-bit you have to give the -m64 option?

Is the eventual plan to use the natural word length of the platform as
the default, i.e. 32-bit on 32-bit and 64-bit on 64-bit, with the option
to force something different using the -m option =C3=A0 la GCC?

THanks.

I'd expect so. Unfortunately, 64-bit support is not mature enough yet to=

make it default.

Yes, but not yet.

Cool, and understandable.  64-bit support needs to be shaken down more
and available on Windows as well as Linux, before any thought of having
a policy of generating for the platform.
