The Chicken 2.41 tarball built on VS71 with nmake -f makefile.vc fails
in the same way. This is not a CMake-specific problem. Rather, it's
either a general problem with eggs on MSVC, which are making an
inappropriate use of a Windows style pathname. My suspicion falls on
_make-pathname in utils.scm, but if there's a platform-specific
behavior, it's not clear to me. I need to start learning about better
tools for perusing Scheme code than just visual inspection. The Scheme
equivalent of a VC++ class browser, really. Suggestions welcome,
although I suppose I'll RTFM about Quack.
