annotate src/console-tty.c @ 5139:a48ef26d87ee
Clean up prototypes for Lisp variables/symbols. Put decls for them with
the other stuff related to the file they're in. In the process, fix a few
places with incorrect initialization of symbols and variables.
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-03-12 Ben Wing <ben@xemacs.org>
* lisp.h:
* lisp.h (redo-symbols): Removed.
Put the Lisp variables and symbols where they belong, with other
stuff related to the file they're in.
* event-Xt.c (THIS_IS_X):
* event-Xt.c (syms_of_event_Xt):
* event-Xt.c (reinit_vars_of_event_Xt):
* event-gtk.c:
* event-gtk.c (syms_of_event_gtk):
* event-gtk.c (reinit_vars_of_event_gtk):
* event-stream.c:
* event-stream.c (syms_of_event_stream):
* event-stream.c (reinit_vars_of_event_stream):
* events.c (reinit_vars_of_events):
* events.c (vars_of_events):
`sans-modifiers' was defsymbol'ed more than once. Move it to
events-stream.c. `self-insert-command' was defsymbol'ed more than once.
Vevent_resource should be staticpro_nodump()ed as it's declared in
a reinit_*() method.
* lread.c (vars_of_lread):
Vfile_domain wasn't staticpro'ed.
* minibuf.c:
* minibuf.c (reinit_complex_vars_of_minibuf):
Vminibuffer_zero and Vecho_area_buffer weren't staticpro'ed.
