Looks like you got pretty far, as most of those are problems in 
phobos, not druntime.  For the last one, try turning maxY into a 
runtime variable, ie replace enum with real, and change that 
static assert to regular assert, ie remove static.  That fixed 
the issue for me on ARM, which was due to CTFE.  Are you 
cross-compiling or compiling on NetBSD itself?

I'll take a look.
