Is there a possiblity to get a cygwin compatible D compiler binary which creates ELF objects just as the pure Linux version does from DigitalMars?
As far as I know the cygwin-included GDC is ancient, the current GDC is not really finished (lots of bugs remain) and the windows DMD only produces some strange OMF object format. I need ELF objects to link with my project using cygwin on Windows.

... what? Cygwin doesn't use ELF, so unless you're using something really strange like my ELF-on-Windows environment something is wrong here.

I think the idea was to produce linux binaries from a compiler on a windows system.

It'd be very cool (and personally, I see no reason it ought to depend on cygwin). A compiler should not be dependent upon its environment to produce compatible binaries.

In an ideal world, I'd just tell the compiler to use its linux backend rather than its windows backend (and to link with linux libraries, located in a directory of my choice). There's no hard and fast reason why the reverse couldn't be true as well, compiling windows binaries from a linux machine.

(NOTE: I am not actually *suggesting* this, because I realize it'd be a gargantuan amount of work. I've just been thinking about this lately, because I need to produce multi-platform binaries, and I'd rather do all my compilation in one place, even if I still need to run acceptance tests on those other platforms.)

A cross-compiler? That's a totally different issue. You can build a GDC cross-compiler, but having a current GDC compiler is neither a prerequisite nor even very helpful. I've made GDC cross-compilers in both of these directions, as well as various others (don't ask X_X )

I build Windows binaries from Linux by running the Windows version of dmd
under Wine on the code. It works pretty well almost out of the box
(some adjustments to sc.ini are all that's needed.)

I don't have any ideas about building Linux bins from Windows though.
