regex-posix includes sources for the C regex library.  However, the 
Cabal package for regex-posix on Hackage doesn't have these sources or 
the configure scripts, presumably because they weren't listed as 
extra-source-files in the .cabal file, so they are only in the darcs 

The darcs repository is at  I 
suggest grabbing that version and using it for the Windows platform 
build. (don't forget to autoconf!)

Chris: can we get an updated regex-posix with the configure scripts and 
C sources on Hackage please?
