- * Also, the problem of determining the amount of memory available
- * is shoved onto the user.

- * Selection of a file name for a temporary file.
- * This is system-dependent!
- *
- * The code as given is suitable for most Unix systems, and it is easily
- * modified for most non-Unix systems.  Some notes:
- *  1.  The temp file is created in the directory named by TEMP_DIRECTORY.
- *      The default value is /usr/tmp, which is the conventional place for
- *      creating large temp files on Unix.  On other systems you'll probably
- *      want to change the file location.  You can do this by editing the
- *      #define, or (preferred) by defining TEMP_DIRECTORY in jconfig.h.
- *
- *  2.  If you need to change the file name as well as its location,
- *      you can override the TEMP_FILE_NAME macro.  (Note that this is
- *      actually a printf format string; it must contain %s and %d.)
- *      Few people should need to do this.
- *
- *  3.  mktemp() is used to ensure that multiple processes running
- *      simultaneously won't select the same file names.  If your system
- *      doesn't have mktemp(), define NO_MKTEMP to do it the hard way.
- *      (If you don't have <errno.h>, also define NO_ERRNO_H.)
- *
- *  4.  You probably want to define NEED_SIGNAL_CATCHER so that cjpeg.c/djpeg.c
- *      will cause the temp files to be removed if you stop the program early.
