No, none at all.  I just thought, since I build GDC from source anyway, I might 
as well see if I can just add an extra couple of config options and get what I 
want.  But it's great to have the ready-made downloads.

Just to know, does the 2.065 version require that I have gcc installed 4.9.0 on 
my system?  Or is the "GCC" column just an indicator of what GCC sources the 
build was based on?

Yes, I'm interested principally in cross-compiling, both for linux-on-ARM and 
bare-metal ARM.

That said, t would be fun to actually have GDC running on an RPi.  I remember 
compiling C++ code on it and the amusing horror of how terribly long it took, it 
will be fun to see how D compilation goes by comparison ... :-)

Thanks, I'll have a read through these. :-)
