I think the right way is to use postConf hook in the Cabal's Setup.lhs. The hook should check whether the BUILD platform is Windows 98 and it can add shfolder to extra-libs field in the hooked build info. Currently I am not sure how to check whether the platform is Windows 98. After all the Setup.lhs should still run under Unix. I wonder how many people still use Windows 98 platform. In my opinion it is too unstable.
As far as I know, it's safe to link to shfolder on all versions of Windows, so the test for Windows 98 specifically should be unnecessary. Only Windows generally needs to be tested for. I see that something like this has been done in package.conf.in, but I don't see what that file is used for. As for supporting Windows 98 at all, I wouldn't hold it against you if ou just didn't bother. I certainly wouldn't bother if I had a more recent version to use or if I could persuade my customer (AKA my wife) to use Linux. It would make my life a little easier of it just worked out of the box though :-) Regards, Toby.
