* cm.c (tputs, tgoto, BC, UP): Remove extern decls. Include tparam.h instead, since it declares them. * cm.h (PC): Remove extern decl; tparam.h now does this. * deps.mk (cm.o, terminfo.o): Depend on tparam.h. * terminfo.c: Include tparam.h, to check interfaces. (tparm): Make 1st arg a const pointer in decl. Put it at top level. (tparam): Adjust signature to match interface in tparam.h; this removes some undefined behavior. Check that outstring and len are zero, which they always are with Emacs. * tparam.h (PC, BC, UP): New extern decls.

tgoto. Not only is the calling sequence different, but the string

format is different too.
