| 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. |
