X-Git-Tag: REL-1-2-0~76
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=1763e0ec11ce3eba4ee3809cc91c21416e70f627;p=m17n%2Fm17n-lib.git

(core_initialized): Delete this variable.
(m17n__core_initialized, m17n__shell_initialized,
m17n__gui_initialized): New variables.
(m17n_init_core, m17n_fini_core): Check m17n__core_initialized
instead of core_initialized.
(m17n_status): New function.
