早期freebsd实现

Mon Nov 30 16:51:33 1992  Per Bothner  ([e-mail])

	* trie.h (class Trie), compact.h (class Compact_Matrix,
	class Compact_Matrix::Row_Node), compact.cc (new method
	Compact_Matrix::init):  Don't use no-longer-allowed
	initialized non-const fields; use constructors instead.

Tue Nov 17 22:00:15 1992  Per Bothner  ([e-mail])

	* compact.cc:  ANSIfy:  bcopy->memcpy, bzero->memset,
	* compact.cc (Compact_Matrix::first_fit_decreasing):  Re-write
	dubious memory allocation using alloca to use
	malloc/realloc/free.  This supposedly fixes an HPUX problem.
	* trie.cc (Trie::output):  Fix to avoid const/non-const
	warning when compiling generated output.

Sun Nov  1 15:58:19 1992  Per Bothner  ([e-mail])

	* trie.cc, compact.cc:   Use "new" placement syntax
	(as in 'new (ARGS) TYPE'), unless  _G_OLD_PLACEMENT.
	* compact.cc:  ANSI-fy:  bcopy->memcpy etc.
	* Makefile.in:  Minor fixes related to using $(C++).

Sat Mar  7 08:48:53 1992  Michael Tiemann  ([e-mail])

	* options.c: Several methods of the class `Options' remained from
	an earlier implementation.  They have now been removed.

Sun Mar  1 17:03:43 1992  Per Bothner  ([e-mail])

	* trie.h (Trie::Trie):  Initialize current_size field.
	* Makefile.in:  Add 'check' rule.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  ([e-mail])

	* Makefile.in, configure.in: removed traces of namesubdir,
	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
	  copyrights to '92, changed some from Cygnus to FSF.

Sat Feb  1 13:40:04 1992  Per Bothner  (bothner at cygnus.com)

	* Rename test.c to test.cc (avoids some problems in
	getting the wrong include files).

Fri Feb 23 19:44:10 1990  Doug Schmidt  (schmidt at zola.ics.uci.edu)

        * Added the `-h' option to print out a verbose help message.

        * Added a check in Trie::output that ensures the program doesn't
          crash if no keywords are given!
          
        * Implemented the -f (generate full trie) option.  This is useful
          to generate another example program for my USENIX C++ paper!

        * Removed the member field `compact_output' from class Trie.  
          Changed all uses of this variable to option[COMPACT].  Why
          was it ever done the other way anyhow?!

        * Added the `-C' CONST option so that user's can declare strings in 
          the generated lookup table to be readonly.

Fri Feb 16 10:47:02 1990  Doug Schmidt  (schmidt at zola.ics.uci.edu)

        * Killed some debugging code in compact.cc (operator new).

Thu Feb 15 23:20:44 1990  Doug Schmidt  (schmidt at zola.ics.uci.edu)

        * Fixed a bunch of incredibly stupid errors.  (I can't believe
          this thing even worked before...).  That's what happens when you
          don't hack for 2 months ;-(
