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