(PF_funcs, Asm_funcs, L_funcs, PAS_funcs, TEX_funcs,
Scheme_funcs, prolog_funcs): renamed to Fortran_functions,
Asm_labels, Lisp_functions, Pascal_functions, Scheme_functions,
TeX_functions, Prolog_functions.
(inf): no more a global variable.
(C_entries): take 2nd parameter `inf' instead of using the global one.
(find_entries): added the cp1 var for optimisation.
(find_entries): added more suffixes for assembler files.
(Asm_funcs): Now finds labels even without an ending colon.
the indesc open was moved inside a fork.
Handle MAIL_USE_LOCKF.
(MAIL_USE_SYSTEM_LOCK): New conditional macro.
Define it if either MAIL_USE_FLOCK or MAIL_USE_LOCKF.
(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.
* etags.c: (C_entries): Keep track of ()-parenthesis level so that
functions returning a pointer to a function, a la `signal', can be
parsed. This also required new state `fstartlist' to `FUNCST'.
(SAVE_TOKEN, RESTORE_TOKEN, TOKEN_SAVED_P): 1-deep token save stack.
(C_entries, CNL): use it to isolate preprocessor directive processing
from the other state engines.
(begtk): add '~', for C++ class destructors.
directory. Only chmod and chgrp files that we installed, which
excludes ${INSTALLABLE_SCRIPTS}. They go in ${bindir}.
(INSTALLFLAGS): Deleted definition, since it is an unused variable now.
* etags.c (C_entries): is_func is initialised here instead of in
consider_token for the sake of the yacc rules section.
(C_entries): Now class, struct, enum, union and typedef produce
named tags.
(L_funcs): the (foo::defmumble stuff now should work.
(consider_token): function returned random value--corrected.
(C_entries): corrected == versus = typo.
* etags.c (FINCST): added the fignore status. Means we are
after the parameter list and before the open curly brace.
Allows correct parsing of C++ constructors.
(C_entries, consider_token): make use of fignore.
(consider_token): reset funcdef when next_token_is_func: when in
ctags mode makes DEFVAR and others work better.
(L_isquote): function that recognises the "(quote" string.
(L_getit): ignore quoting via "'" or "(quote". Useful for defalias.
(main): now calls xnew instead of alloca for portability.
(../src/config.h): included only if HAVE_CONFIG_H.
(const): void definition removed--config.h takes care of it.
(consider_token): DEFUNs now treated like funcs in ctags mode.
(LEVEL_OK_FOR_FUNCDEF): removed.
(C_entries): optimized the test that used LEVEL_OK_FOR_FUNCDEF.
(C_entries): removed a piece of useless code.
(C_entries): making typedef tags is delayed until a semicolon
is met. This handles "typedef int X, Y, Z;" correctly.
