(main): don't allow the use of -t and -T in etags mode.
(print_help): don't show options enabled by default.
(print_version): show the emacs version number if VERSION is #defined.
(find_entries): add "ss" as suffix for Chez Scheme.
(relative_filename, absolute_filename, absolute_dirname):
functions added to compute filenames in tags files.
(process_file): filenames in tags file are relative to the
directory where the tags file is (useful with the -o option).
(main): initialise the outfiledir var.
(TYPEDST): added the `tignore' value.
(C_entries): corrected various small bugs.
(longopts, print_help, main, process_file): put absolute filenames
in the tag file if the -A --absolute-pathnames option is used.
(print_help): alfabetically order the options.
(malloc, realloc, strcpy, strncpy, strcmp): remove extern declar.
(schedule): Don't return a value.
(sigcatch): Reestablish the handler first.
(getevent): Always call notify at the end.
(notify): Defer alarms around the whole body of function.
(main): Don't request SIGIO, and don't handle it.
Loop calling getevent.
(sigcatch): Delete code to handle SIGIO.
If defer_alarms is set, don't call notify, just set alarm_deferred.
(getevent): Use read, not getchar. Handle EINTR and EAGAIN.
Set defer_alarms around realloc and schedule.
If alarm_deferred gets set, call notify.
Likewise if this event is the only pending event.
Make buf and buf_size global variables.
Don't malloc buf if it is already non-zero.
(schedule): Just exit if run out of memory.
Return the number of events.
(signal) [_CX_UX]: Add #undef.
(write_c_args): Take new arg FUNC. Make output look like lisp call
prototypes: (function ARG1 ARG2), upcasing arg names.
(scan_c_file): Pass BUF to write_c_args for FUNC arg.
stab_type, add_keyword, C_reate_stab, C_create_stabs): deleted.
Use gperf generated hash table instead of linked list.
(C_stab_entry, hash, in_word_set, get_C_stab, C_symtype): added.
Mostly code generated by gperf.
(consider_token): removed unused parameter `lp'.
(PF_funcs, getit): allow subroutine and similar declarations
to span multiple lines.
(C_entries): check for newline if inchar to avoid bus errors.
(process_file, find_entries): distinguish among nonexistent
and not regular file.
