DMD 64bit Status?

[Jonathan Crapuchettes]

Can anyone tell me the status of the DMD 64bit compiler? I'm going to be working 
on a project in the next month that will involve 18,000 x 18,000 double 
matrices. 32bit will only allow me to work with 1 at a time and I need to be 
able to handle minimum of 2 at a time. I have thought of using LDC, but that 
would require rewriting 10,000 lines of code to work with Tango instead of Phobos.

Thank you,
JC
