Needed a bit of R&R so I started on merging 2.061 D frontend into 
GDC last night.

The only urk I've hit so far is that someone thought it might be 
a good idea to define a ulonglong and longlong type in a place 
that doesn't exist in gdc's copy of the dfrontend.  But given 
that I've expressed positive views on moving towards minimising 
the use of #ifdef's in the app code.  Rather than removing the 
use of this, I've done the following changes my side to try and 
suppliment this.

- Removed some #ifdefs for GDC in the D frontend.
- Moved over d-gcc-complex_t.h to complex_t.h, moved about some 
includes in mars.h.
- Created a port.c/port.h and started implementing hooks for gcc 
backend.
- Created a new target.c/target.h and started defining some new 
hooks to reduce some more #ifdef'd code in the dfrontend.


For successfully porting port.h over to gdc, the main problem is 
with using gcc's real_t implementation instead of float, double 
that dmd uses is that the real_t implementation relies on some 
typedefs in mars.h (for dint64_t, etc), so these will need to be 
moved out to somewhere else...

Would a target.h header be fine for this?  Or do you have 
somewhere else in mind.

Once I've finished the changes, I'll send a pull request of the 
initial work for the next release.

Thanks,
Iain.
