* complaints.c: New file, code moved from utils.c.
* complaints.c (complain): Made into a varargs function. * complaints.h: New file, code moved from symfile.h. * Makefile.in (SFILES_MAINDIR): Add complaints.c. * Makefile.in (HFILES): Add complaints.h. * Makefile.in (OBS): Add complaints.o. * symfile.c (complaint_root, stop_whining, complaint_series, complain, clear_complaints, add_show_from_set for stop_whining): Moved to complaints.c. * symfile.h (struct complaint, complaint_root decl, complain prototype, clear_complaints prototype): Moved to complaints.h. * buildsym.c, coffread.c, dbxread.c, dwarfread.c, elfread.c, gdbtypes.c, mipsread.c, stbsread.c, symfile.c: Include complaints.h. Remove casts from arguments to complain(), which is now a varargs function, and remove unnecessary placeholder zero args. * defs.h (begin_line): Add prototype. * defs.h (vprintf_filtered): Add prototype. * dwarfread.c (varargs.h): Remove, no longer needed. * dwarfread.c (dwarfwarn): Remove prototype and function. * dwarfread.c (complaints): Define a bunch of complaints. * dwarfread.c (SQUAWK): Remove macro defs, convert all usages to standard complain() calls. * utils.c (begin_line): New function that ensures that whatever gets filter-printed next starts on its own line. * utils.c (vprintf_filtered): New func, like vfprintf_filtered, but to stdout (calls vfprintf_filtered internally).
