to make prototypes for all functions declared here.
* cplus-dem.c: Avoid declaring xmalloc and xrealloc.
* c-exp.y: Rename SIGNED, OR, and AND to avoid conflict.
* environ.c: Include <stdio.h> before defs.h. Minor cleanup.
* ieee-float.h: Use PARAMS for prototypes; make some params const.
* ieee-float.c, valarith.c: Include <stdio.h>. Lint. b*=>mem*.
* m2-exp.y: Remove unused CONST; Rename OR and AND.
* utils.c: Avoid declaring malloc and realloc. Lint.
(request_quit): Accept signal-number parameter.
* cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
* infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
(This still doesn't seem to make MIPS bkpts work.)
* mipsread.c: Remove dup "Reading symbol data..." msg.
(symbol_file_command, add_file_command): Remove, obsol.
* printcmd.c (ptype_command): Say "an enum" rather than "a enum".
Wrap output appropriately.
* stack.c (locals_info, catch_info, args_info): Check
selected_frame rather than target_has_stack or coredumping.
* valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
enums appropriately.
