Hi David,

Thanks for your reaction !

That's exactly what i was looking for :-) Would it be possible to 
get the LDC c++ based version of 2.068.2 committed to the dmd 
repo (something like '2.068.3' or maybe even as a new version of 
'dmd-cxx'), so that i can rebase my 'dragonflybsd_v2.068.2' 
changes on top of that later on ? As your changes have already 
been proven to work, it should be easier to get it accepted.

Figuring out which branch to use during porting is making the 
porting process a little cumbersome.

@Iain: as dmd-cxx is not able to compile the current 'master' and 
'2.068.2' is, would it make sense to replace the current dmd-cxx 
with the LDC version c++ based of 2.068.2 ? I know you did quite 
a bit of work backporting several patches to dmd-cxx. I am just 
trying to help simplify porting of dmd to new platforms. And 
having only to stages would make all of this a lot easier.

Regards,

Diederik
