Apparently glob_wrapper() isn't sufficiently platform-independent. I'm not sure if this is a POSIX thing or what. It was an experimental function which is not used anyway, so I removed the test and improved the documentation. I'm closing the issue, since the tests pass now, but I've added also it to the list of future improvements. It could be that the best thing to do is have configure.ac detect, in some what, whether or not this sort of function works. Let me know if there is anything else.
