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. 7 8 Copyright 2000, 2001, 2007, 2010 Free Software Foundation, Inc. 9 10This file is part of BFD, the Binary File Descriptor library. 11 12This program is free software; you can redistribute it and/or modify 13it under the terms of the GNU General Public License as published by 14the Free Software Foundation; either version 2 of the License, or 15(at your option) any later version. 16 17This program is distributed in the hope that it will be useful, 18but WITHOUT ANY WARRANTY; without even the implied warranty of 19MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
