/* 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.
