Subject: * com_err.h (add_error_table, remove_error_table): Annotate as modifying
X-Git-Tag: krb5-1.3-alpha1~1714
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5f337297f9e6f6f22473e6226c41b8a105c4dbab;p=krb5.git

* com_err.h (add_error_table, remove_error_table): Annotate as modifying
internal state.
(struct et_list, _et_list): Remove.

* error_table.h (struct et_list, _et_list): Put back here.

* error_message.c (add_error_table, remove_error_table): Annotate specific
modifications.  Disable inconsistent-defifition checks since _et_list isn't
describe in the header file but is global and modified.

* et_c.awk: Make the generated initialization function simply call
add_error_table, and drop the static linked-list node.
