Hi all,
The only problem stalling the release of the Windows installer for the new Haskell Platform is the bug in regex-posix. It compiles fine (using the libregex.a library from MinGW), but fails at runtime with the following error:

You can't load a .a library into GHCi, so you need to get the regex implementation from somewhere. Is there a DLL? If not, you'll have to arrange to put the code into a .o that GHCi can load. Cheers, Simon
