Is there some reason to believe that your ugly hack ("C:\\") is going to be more robust than my ugly hack ("C:\\ ")? If so, I'll change mine. I still consider this a bug in Unix.opendir, because the implementation does not match the documentation (the Ocaml documentation, not the VC++ documentation). I hope you will fix it, either by implementing the ugly hack so I don't have to, or by changing the documentation so that the implementation matches the spec. Thanks, Trevor

That would be wonderful -- I hate to install VC++, it is a fat hog. And, I need to install Cygwin anyway, I use it for make, bash, and some other things. So, it gets my vote. I would be happy to be a beta tester if you decide to make the change. -Trevor

I don't know, except that "my" hack is the one suggested by the MSDN documentation. > I still consider this a bug in Unix.opendir, because the > implementation does not match the documentation (the Ocaml > documentation, not the VC++ documentation).

The best fix I see is to dump VC++ entirely and go with Cygwin, whose Unix emulation library is much better than anything we could write. It seems Cygwin made progress recently on the thread-safety issue, so the last obstacle to using Cygwin might be disappearing. - Xavier Leroy
