The underlying JVM abstraction (java.io.File) helps a bit with smoothing over these differences, but the essential difference is that the DOS drive letter (e.g. "C:") is mapped to the Pathanme DEVICE component IFF we're executing on Windows. And the ABCL Pathanme name string *always* canonicalizes the directory separator to forward slashes ("/") regardless of runtime platform. In general, we try to DWIM on most operations but there are some corner cases, such as deserializing name strings on different platforms where the implementation can run into lacunae.

Hmmm. We were gonna release abcl-1.0.0 on October 22, 2011 for ECLM. Should we trying upgrading to 2.017.22 before the release? I need to look at the changes in ASDF…
