| /* 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. |
