I have uploaded a new GHC InstallShield for Windows that fixes many recent problems (including most of the problems with GHC that Mike Thomas reported in his list of instructions for building H/Direct). Unless the Cygwin team have acted with unwonted rapidity (which, at the time of writing, they hadn't), you'll also need to download our version of the mingwin package (or get the relevant bits from SourceForge). Our zip can simply be unpacked over an installed Cygwin tree to give you mingwin headers and libraries that really work. -- http://sc3d.org/rrt/ | certain, a. insufficiently analysed
