Could anybody explain would it hard to create port DMD to 
HelenOS, and what needed for it?

It depends on how Posix-compliant it is.  D is mostly run on 
Posix-ish systems, like linux, OS X, or BSD, and on Windows.  I 
don't know how much dmd itself relies on such OS APIs, but 
druntime/phobos certainly do.

It may not be certified as fully Posix-compliant, but it 
certainly seems to have some support.  The open question is how 
much it supports the parts that dmd/druntime/phobos use.

i don't remember if it has proper TLS support. and what the state of
posix emulation libraries there.

the basic questions are TLS support and threading support (how easy it
will be to support pause semantics required by current GC
implementation). everything other is a tedious work of writing wrappers
for "traditional" system calls, boring but doable.

i believe that is shouldn't be very hard though.
