Subject: * xterm.h: New section for declarations for xfaces.c.
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1^2~5^2~95983
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:///%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:/?a=commitdiff_plain;h=bf489d26face57127fb118eb3b6c18189c6fab5c;p=emacs.git

* xterm.h: New section for declarations for xfaces.c.
	(init_frame_faces, free_frame_faces, intern_face,
	face_name_id_number, same_size_fonts, recompute_basic_faces,
	compute_char_face, compute_glyph_face): Declare these here.
	* xfaces.c (same_size_fonts): We can now remove this extern
	declaration.
	* xfns.c (face_name_id_number): Likewise.
	* xterm.c (intern_face): Likewise.
