Linker error with array expressions

Of course I would time the code; as it stands though, the version with array operations doesn't even compile (or link, rather), due to the bug I reported.

I would like to use LDC, but my main target platform is Windows, and consensus seems to be that LDC isn't usable there. Or is it possible to use it if I don't need exception handling? Can it generate DLLs? In any case, no LDC binaries for Windows seem to be available.

What's the status with GDC? I think it was resurrected a while back; is there a current version available? Again, Windows?

As far as I can tell at this point, I'm stuck with DMD for Windows development, for better or for worse. For now, I'll probably revert to loops for the offending code sections and replace them with hand-written inline SSE assembly if profiling shows a need for this. The simple loops I'm using here shouldn't be hard to write by hand. Still, it would be great if at some point DMD could do it by itself. Probably a distant dream at this point...
