 * $Log: storage.h,v $
 * Revision 1.5  1998/12/14 13:19:00  nop
 * Merge UNSAFE_OPTS (ref fixups); fix Log tag placement to fit CVS whims
 *
 * Revision 1.4  1998/02/19 07:36:17  nop
 * Initial string interning during db load.
 *
 * Revision 1.3  1997/07/07 03:24:55  nop
 * Merge UNSAFE_OPTS (r5) after extensive testing.
 *
 * Revision 1.2.2.4  1997/05/29 20:47:33  nop
 * Stupid hack to allow non-gcc compilers to use -Dinline= to make the server
 * compile.
 *
 * Revision 1.2.2.3  1997/05/20 03:01:34  nop
 * parse_into_words was allocating pointers to strings as strings.  Predictably,
 * the refcount prepend code was not prepared for this, causing unaligned memory
 * access on the Alpha.  Added new M_STRING_PTRS allocation class that could
 * be renamed to something better, perhaps.
 *
 * Revision 1.2.2.2  1997/03/21 15:19:24  bjj
 * add myrealloc interface, inline free_str
 *
 * Revision 1.2.2.1  1997/03/20 07:26:04  nop
 * First pass at the new verb cache.  Some ugly code inside.
 *
 * Revision 1.2  1997/03/03 04:19:27  nop
 * GNU Indent normalization
 *
 * Revision 1.1.1.1  1997/03/03 03:45:04  nop
 * LambdaMOO 1.8.0p5
 *
 * Revision 2.1  1996/02/08  06:13:09  pavel
 * Added M_FLOAT, removed unused M_PI.  Updated copyright notice for 1996.
 * Release 1.8.0beta1.
 *
 * Revision 2.0  1995/11/30  04:55:11  pavel

 * Added copyright notice.
 *
 * Revision 1.6  1992/10/21  03:02:35  pavel
 * Converted to use new automatic configuration system.
 *
 * Revision 1.5  1992/10/17  20:53:28  pavel
 * Global rename of strdup->str_dup, strref->str_ref, vardup->var_dup, and
 * varref->var_ref, to avoid conflict on systems that provide their own
 * definition of strdup().
 *
 * Revision 1.4  1992/09/14  17:39:30  pjames
 * Moved db_modification code to db modules.
 *
 * Revision 1.3  1992/08/31  22:23:29  pjames
 * Changed some `char *'s to `const char *'
 *
 * Revision 1.2  1992/08/28  16:25:17  pjames
 * Added memory types for refcount module.  Added `strref()' and `free_str()'.
 *
 * Revision 1.1  1992/08/10  16:20:00  pjames
 * Initial RCS-controlled version
