    Option for showing input string in list of anagrams.
    
    Added a flag without which wordplay removes the input string from the list of possible anagrams.

    Remove hardcoded compiler
    
    Remove the hardcoded compiler from makefile
    so other compilers can be used and cflags can be passed.

commit 0d362f2a26021599d65904b9465e566a09ea92b0

    Include stdlib.h
    
    There are implicit function declarations in wordplay.c.
    These "might hide issues the compiler could otherwise
    warn about or cause bad code," so they should probably
    be patched.

03-20-96 Fixed a small memory allocation problem.  In a couple of places,
	 the amount allocated to hold character strings was not taking the
	 space to store the null into account.  This bug has only affected
	 a couple of people.  
09-11-95 In the anagramr7 function, I check the product of the maximum
	 "levels deep" remaining and the length of the longest candidate
	 word.  If this product is less than the length of the string
	 passed in, a "dead end" condition exists.  This makes the program
	 run significantly faster for longer strings if the maximum
	 depth option is used.
08-21-94 Added "wordfile from stdin" option using "-f -"  
	 Fixed "4" bug.  Digits in a string disqualify the string.
	 Vowel-check override option added.
	 Starting word ("w" option) checked to see if it's an anagram
	 of the initial string.
08-16-94 Used integer masks representing which letters appear in each
	 word, allowing extraction checking to be checked quickly for
	 failure in the anagramr7 routine.  Result:  the program has
	 been 4 to 5 times faster.
08-14-94 Made the program much more memory efficient.  Instead of calling
	 malloc for each word in the candidate word list and in the key
	 list, a contiguous block of memory was allocated to hold the
	 words.  The block is realloc'ed if it needs to be increased as
	 the words are read in.  After the words are packed into the
	 block, the pointers are allocated and are pointed to the
	 appropriate places (beginnings of words) in the block, so the
	 rest of the program works with no modification.  Two gigantic
	 arrays that weren't being used were eliminated.  The word length
	 index arrays are now made to be the size of the longest word 
	 instead of MAX_WORDS.  In fact, MAX_WORDS is now obsolete.
07-14-94 Added "silent" option.
06-03-94 Added "#include <ctypes.h>" so it would work on BSD/386 .  Thanks
         to mcintyre@io.com (James Michael Stewart) for reporting the bug.
05-26-94 Fixed command-line parsing bug.
05-25-94 Eliminated redundant permutations.  Added option to specify a
	 word to appear in anagrams.  Added maximum depth option (number
	 of words, maximum, to appear in an anagram).  
05-24-94 Added option so user could specify whether to allow anagrams
	 with adjacent duplicate words like "A A" or "DOG DOG".
05-16-94 Made a second copy of the word list and sorted each word's
	 letters alphabetically and sorted this list of keys alphabetically.
	 Modified the recursive algorithm to use the new index. (Ver 6.00)
05-16-94 Another little bug fix.  Someone found that, on their machine,
	 if there are no candidate words loaded for the string being 
         anagrammed, it causes an error when malloc gets passed a zero
         value for the amount to allocate.
05-13-94 Tiny bug fix.  Just a small bug that never actually caused a
	 crash, but very well could have if it had wanted to.  :-)
04-25-94 Speed increase.  If exts indicates extraction was impossible,
	 continue (try next word) instead of executing rest of loop body.
04-21-91 Ron Gregory found a simple bug that has been in all the C
	 versions (4.00 through 5.20).  In the one-word anagram
	 section, a less than should have been a less than or equal to.
	 A simple fencepost error.  The recursive anagram procedure had
	 a similar problem.  A severe error was fixed in the version
	 5.20 read routine which caused the program not to read the
	 wordfile correctly if the entries were lowercase.
04-17-94 Since this program, since it was ported to C, is command-line
	 based, and only anagrams one string, it is not necessary to
	 store the wordlist internally.  Unnecessary words are weeded
	 out as the list is being read, using the "extract" routine.
	 I can't believe I didn't think of using that routine for that
	 purpose sooner.  That means pass1 and pass2 are obsolete.
04-14-94 Changed the "extract" function to use pointers instead of
	 array notation.  Under some compilers, this may nearly double
	 the execution speed of the recursive anagram procedure.  On
	 other compilers, it may make no difference at all.
04-11-94 Added the minimum and maximum candidate word length options
	 that were available in version 3.00 when the program was 
	 interactive.  This helps to narrow down the word list and
	 eliminate a lot of short words when anagramming long strings.
11-30-93 Fixed a bug that Versions 5.00 and 5.01 had.  If there were
	 no words in the candidate word list with the same length as
	 the string passed to anagramr, the string passed to anagramr
	 would not be anagrammed, causing many possible anagrams to
	 be missed.
11-08-93 Eliminated anagrams consisting of the same word occurring 
         multiple times in a row, such "IS IS ...", since interesting
         anagrams rarely contain such repetitions. (Version 5.01)
11-08-93 Debug print statements commented and output cleaned up.
         Version 5.00 completed.  It is currently not known which is
	 always faster:  the old iterative 2 and 3 word anagram options
	 or the recursive algorithm.  All the options from version 4.00
	 are still in the program.
11-07-93 Recursive algorithm working!
11-03-93 Added code to index the candidate word list by number of vowels
	 per word. (Beginning of 5.00 Alpha)  Never used in Version 5.00,
	 but the code is there for future use.
05-25-93 Three word anagramming capability ported and added.
04-30-93 The big port from FORTRAN 77 to ANSI C.  No longer interactive.
	 Instead, arguments are taken from the command line.
	 (Everything working except three-word anagrams and all command
	 line options not yet implemented)
