/* 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.
|
|
*
|
|
* This was based on filenames.h from BFD, the Binary File Descriptor
|
|
* library, Copyright (C) 2000-2016 Free Software Foundation, Inc.,
|
|
* and changed by O. Sezer <sezero@users.sourceforge.net> for our needs.
