The darcs-1.0.9 executables were actually built by Will Glozer, and I  
downloaded them from here:

http://glozer.net/darcs/

I don't know off the top of my head if libcurl is statically linked in.

strings ./realdarcs.exe | grep -i curl

suggests that it is.

It would be cool if darcs --exact-version would emit the  
configuration options that were used to configure it.
