WinHugs May 2006, missing Regex.Posix.dll

[Neil Mitchell]

Hi,

In order to try and crush any more bug reports of the form "libary
doesn't work with WinHugs", I have just loaded every single .hs file
distributed with WinHugs, and seen which fail. Here is a list of the
error message:

I have also uploaded my makefile log at:
http://www-users.cs.york.ac.uk/~ndm/temp/winhugs-make.txt

The HaXML errors mainly stem from Xml2Haskell, which doesnt' appear
anywhere in the makefile logs. I guess the cpphs errors come from the
libraries path setting which is currently:

.;..;..\..;{Hugs}\packages\*

(I added ..\..)

Adding: ..\..\.. to the path makes the cpphs pass

Perhaps Hugs should be default search in this manner, if you are 3
dots deep, then move up 3 dots before considering this the current
search folder? Yhc has this behaviour, GHC does not, but its very
useful!

Thanks

Neil
