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

I think a target.h/target.c would be a good addition. In general, I'd like to see all #ifdef's removed from the main dmd source code. Host and target specific behaviors should be abstracted out, like what root/port.h attempts to do.



OK, well I've started it off with Target::typesize, ::typealign, ::fieldalign.  Maybe also ::fieldoffset, though gdc currently uses the D frontend code to get that that with no known issues (only way to find out is when we start expanding D2 to more targets).

And left it with the comment:  This file contains a data structure that describes a back-end target. At present it is incomplete, but in future it should grow to contain most or all target machine and target O/S specific information.
