  1. /* Macros for taking apart, interpreting and processing file names.
  2.  
  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.
