GDC, seems like its mostly "build from source" kind of thing.
Moved to gitbub:
https://github.com/D-Programming-GDC
(See also newsgroup digitalmars.d.D.gnu)

GDC binaries for Windows TDM-GCC toolchain are still available there:
https://bitbucket.org/goshawk/gdc/downloads

AFAIK it needs 4.6.1 version of TDM toolset.


LDC(2), recent release with binaries.

Both compilers ship dmd-style compiler driver called gdmd or ldmd2.
Speed is mostly what you'd expect of GCC and LLVM respectively.
