+/* Macros for taking apart, interpreting and processing file names.
+
+   These are here because some non-Posix (a.k.a. DOSish) systems have
+   drive letter brain-damage at the beginning of an absolute file name,
+   use forward- and back-slash in path names interchangeably, and
+   some of them have case-insensitive file names.
