 *
 * Revision 1.19  1999/01/03  01:46:44  geoff

 * Rename sethtmltags to init_keyword_table, and simplify the argument
 * list.
 *
 * Revision 1.17  1997/12/02  06:25:07  geoff
 * Get rid of some compile options that really shouldn't be optional.
 *
 * Revision 1.16  1997/12/01  00:53:54  geoff
 * Add HTML declarations.
 *
 * Revision 1.15  1994/10/25  05:46:38  geoff

 * Don't undef P unless we're going to redefine it
 *
 * Revision 1.9  1994/02/07  08:10:47  geoff
 * Add the GENERATE_LIBRARY_PROTOS option.  Put the definitions of
 * index/rindex back the way they were, because that's what's needed on
 * my system (sigh).
 *
 * Revision 1.8  1994/02/07  05:45:25  geoff
 * Change the second parameter of index/rindex to be a char
