Thanks.

We can remove phobos easily but the runtime must be custom, which 
requires recompiling with the appropriate compilers.

How much hacking have you had to do? is it mainly just removing 
bits of code or did you have to do extensive work? and if so, 
what areas, if you recall?

Did you having any major problems messing around with this stuff 
or is it pretty straight forward?
