2001-02-02 Keisuke Nishida <kxn30@po.cwru.edu>
* dump.c, dump.h: New files.
* Makefile.am: Added dump.c, dump.h, dump.x, dump.doc.
* init.c: #include "libguile/dump.h".
(scm_init_guile_1): Call scm_init_dump.
* smob.h (scm_smob_descriptor): New slots: dump_mark,
dump_dealloc, dump_store, undump_alloc, undump_restore,
undump_init.
* smob.c (scm_make_smob_type): Init the new slots.
(scm_set_smob_dump, scm_set_smob_undump): New functions.
* smob.h (scm_set_smob_dump, scm_set_smob_undump): Declared.
* keywords.c: #include "libguile/dump.h".
(keyword_dealloc, keyword_alloc): New functions.
(scm_init_keywords): Set smob_dump and smob_undump.
2001-02-01 Keisuke Nishida <kxn30@po.cwru.edu>
* vectors.c (scm_c_make_vector): New function.
