*
* Revision 1.3 2003/01/29 05:50:12 hippietrail
*
* Fixed my mess in EncodingManager.
* Changed many C casts to C++ casts.
*
* Revision 1.2 2003/01/25 03:16:05 hippietrail
*
* An UT_ICONV_INVALID fix which escaped the last commit.
*
* Revision 1.1 2003/01/24 05:52:34 hippietrail
*
* Refactored ispell code. Old ispell global variables had been put into
* an allocated structure, a pointer to which was passed to many functions.
* I have now made all such functions and variables private members of the
* ISpellChecker class. It was C OO, now it's C++ OO.
*
* I've fixed the makefiles and tested compilation but am unable to test
* operation. Please back out my changes if they cause problems which
* are not obvious or easy to fix.
*
* Revision 1.12 2003/01/06 18:48:39 dom
* ispell cleanup, start of using new 'add' save features
*
* Revision 1.11 2002/09/19 05:31:17 hippietrail
*
* More Ispell cleanup. Conditional globals and DEREF macros are removed.
* K&R function declarations removed, converted to Doxygen style comments
* where possible. No code has been changed (I hope). Compiles for me but
* unable to test.
*
* Revision 1.10 2002/09/17 03:03:30 hippietrail
*
* After seeking permission on the developer list I've reformatted all the
* spelling source which seemed to have parts which used 2, 3, 4, and 8
* spaces for tabs. It should all look good with our standard 4-space
* tabs now.
* I've concentrated just on indentation in the actual code. More prettying
* could be done.
* * NO code changes were made *
*
* Revision 1.9 2002/09/13 17:20:13 mpritchett
* Fix more warnings for Linux build
*
* Revision 1.8 2002/05/03 09:49:43 fjfranklin
* o hash downloader update (Gabriel Gerhardsson)
* - Comment out the "Can't open <dictionary>" printf.
* - Make the progressbar more clean at the begining of the download.
* - Add support for tarballs that doesn't have the full path included
* - Fix copyright headers on the newly added files (*HashDownloader.*)
*
* Revision 1.7 2001/08/27 19:06:30 dom
* Lots of compilation fixes
*
* Revision 1.6 2001/08/10 18:32:40 dom
* Spelling and iconv updates. god, i hate iconv
*
* Revision 1.5 2001/08/10 09:57:49 hub
* Patch by sobomax@FreeBSD.org
* #include "iconv.h" directive is missed from src/other/spell/xp/lookup.c and
* src/wp/impexp/xp/ie_imp_RTF.cpp.
* See bug 1823
*
* Revision 1.4 2001/07/18 17:46:01 dom
* Module changes, and fix compiler warnings
*
* Revision 1.3 2001/06/12 21:32:49 dom
* More ispell work...
*
* Revision 1.2 2001/05/12 16:05:42 thomasf
* Big pseudo changes to ispell to make it pass around a structure rather
* than rely on all sorts of gloabals willy nilly here and there. Also
* fixed our spelling class to work with accepting suggestions once more.
* This code is dirty, gross and ugly (not to mention still not supporting
* multiple hash sized just yet) but it works on my machine and will no
* doubt break other machines.
*
* Revision 1.1 2001/04/15 16:01:24 tomas_f
* moving to spell/xp
*
* Revision 1.7 1999/09/29 23:33:32 justin
* Updates to the underlying ispell-based code to support suggested corrections.
*
* Revision 1.6 1999/04/13 17:12:51 jeff
* Applied "Darren O. Benham" <gecko@benham.net> spell check changes.
* Fixed crash on Win32 with the new code.
*
* Revision 1.5 1999/01/07 01:07:48 paul
* Fixed spell leaks.
*
* Revision 1.5 1999/01/07 01:07:48 paul
* Fixed spell leaks.
*
* Revision 1.4 1998/12/29 14:55:33 eric
*
* I've doctored the ispell code pretty extensively here. It is now
* warning-free on Win32. It also *works* on Win32 now, since I
* replaced all the I/O calls with ANSI standard ones.
*
* Revision 1.3 1998/12/28 23:11:30 eric
*
* modified spell code and integration to build on Windows.
* This is still a hack.
*
* Actually, it doesn't yet WORK on Windows. It just builds.
* SpellCheckInit is failing for some reason.
*
* Revision 1.2 1998/12/28 22:16:22 eric
*
* These changes begin to incorporate the spell checker into AbiWord. Most
* of this is a hack.
*
* 1. added other/spell to the -I list in config/abi_defs
* 2. replaced other/spell/Makefile with one which is more like
* our build system.
* 3. added other/spell to other/Makefile so that the build will now
* dive down and build the spell check library.
* 4. added the AbiSpell library to the Makefiles in wp/main
* 5. added a call to SpellCheckInit in wp/main/unix/UnixMain.cpp.
* This call is a HACK and should be replaced with something
* proper later.
* 6. added code to fv_View.cpp as follows:
* whenever you double-click on a word, the spell checker
* verifies that word and prints its status to stdout.
*
* Caveats:
* 1. This will break the Windows build. I'm going to work on fixing it
* now.
* 2. This only works if your dictionary is in /usr/lib/ispell/american.hash.
* The dictionary location is currently hard-coded. This will be
* fixed as well.
*
* Anyway, such as it is, it works.
*
* Revision 1.1 1998/12/28 18:04:43 davet
* Spell checker code stripped from ispell. At this point, there are
* two external routines... the Init routine, and a check-a-word routine
* which returns a boolean value, and takes a 16 bit char string.
* The code resembles the ispell code as much as possible still.
*
* Revision 1.42 1995/01/08 23:23:42 geoff
* Support MSDOS_BINARY_OPEN when opening the hash file to read it in.
*
* Revision 1.41 1994/01/25 07:11:51 geoff
* Get rid of all old RCS log lines in preparation for the 3.1 release.
*
