+ * 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.
