/* Modified September, 1995, Amy A. Lewis

 * 1: removed all file-locking dreck.  Unnecessary

 * 2: Fixed bug that made fortune -f report a different list than

 *        fortune with any other parameters, or none, and which forced

 *        the program to read only one file (named 'fortunes')

 * 3: removed the unnecessary print_file_list()

 * 4: Added "OFFDIR" to pathnames.h as the directory in which offensive

 *        fortunes are kept.  This considerably simplifies our life by

 *        permitting us to dispense with a lot of silly tests for the string

 *        "-o" at the end of a filename.

 * 5: I think the problems with trying to find filenames were fixed by

 *        the change in the way that offensive files are defined.  Two birds,

 *        one stone!

 * 6: Calculated probabilities for all files, so that -f will print them.

/* Modified May 1997, Dennis L. Clark (dbugger@progsoc.uts.edu.au)

 *      + Various portability fixes

 *      + Percent selection of files with -a now works on datafiles which

 *        appear in both unoffensive and offensive directories (see man page

 *        for details)

 *      + The -s and -l options are now more consistant in their

 *        interpretation of fortune length

 *      + The -s and -l options can now be combined wit the -m option

/* Modified August 2001, Takahiro Nagao(nyagao@longtail.co.jp)

 *  + ported to Windows

 *  + if -n NUM is too small or too large, now it doesn't cause infinite loop

 *    (see init_prob())

 *  + -f xx% dir now should report correct percentage (see print_list())

 *  + added -z to report file and pos
