2*20fce977Smiod 
3*20fce977Smiod    These are here because some non-Posix (a.k.a. DOSish) systems have
4*20fce977Smiod    drive letter brain-damage at the beginning of an absolute file name,
5*20fce977Smiod    use forward- and back-slash in path names interchangeably, and
6*20fce977Smiod    some of them have case-insensitive file names.
