 * This section provides portable defines for large file support.
 * To use this you must compile your code with _LARGEFILE64_SOURCE
 * defined and use the KDE_xxx defines instead of the normal
 * C functions and structures.
 *
 * Please note that not every platform supports 64 bit file structures,
 * in that case the normal 32 bit functions will be used.
 *
 * @see http://www.suse.de/~aj/linux_lfs.html
 * @see http://ftp.sas.com/standards/large.file/xopen/x_open.05Mar96.html
 *
 * KDE makes use of the "Transitional Extensions" since we can not ensure
 * that all modules and libraries used by KDE will be compiled with
 * 64-bit support.
