Subject: (open_chise_data_source_maybe): New implementation; don't use
X-Git-Url: http://git.chise.org/gitweb/?p=chise%2Fxemacs-chise.git.1;a=commitdiff_plain;h=75e5181a9626c8bbbe57c1b8c6a6a04ec2b9597c

(open_chise_data_source_maybe): New implementation; don't use
`build_string' and `Fexpand_file_name' to avoid GC.
(char_table_get_db_cos): New function when HAVE_LIBCHISE is defined.
(load_char_attribute_maybe_cos): Likewise.
