* cppinit.c (install_predefs): Delete function.
(cpp_start_read): Don't call install_predefs.
(cpp_handle_option): Remove case 'u' and all refs to
opts->inhibit_predefs.
(print_help): Don't mention -undef.
(initialize_builtins): Define __HAVE_BUILTIN_SETJMP__, to
match cccp.
* cpplib.h (struct cpp_options): Remove inhibit_predefs
member.
* cccp.c (predefs): Delete variable.
(main): Remove case 'u' in argument parse loop,
'inhibit_predefs' variable, and the code block that would
process CPP_PREDEFINES.
(initialize_builtins): Don't define __OBJC__, the driver will
do that.
* gcc.c (default_compilers): Remove -undef from all specs that
invoke a C preprocessor.
* ch/lang-specs.h: Likewise.
* cp/lang-specs.h: Likewise.
* f/lang-specs.h: Likewise.

* cppfiles.c (read_and_prescan): Map backslash-newline to '\r'
(which cannot otherwise appear in the processed buffer) and
move it out of tokens that it appears in the middle of.
Improve performance.
(find_position): New function.
* cpplib.c: \r (one character) indicates backslash
newline, not \\\n (two characters). It cannot appear in the
middle of a token. Call CPP_BUMP_LINE (pfile) whenever
parsing moves past \n or \r. Increment pfile->lineno whenever
a \n is placed into token_buffer. Only one mark can exist at
a time, and CPP_BUMP_LINE must not be used while it is
active. It is automatically cleared by cpp_pop_buffer and
parse_goto_mark. \r is not in is_hor_space or is_space.
(NEWLINE_FIX, NEWLINE_FIX1, adjust_position,
update_position, count_newlines, parse_move_mark): Removed.
(parse_string, copy_comment): New functions.
(parse_name): Returns void.
(parse_set_mark, parse_clear_mark, parse_goto_mark): Take only
one argument, a cpp_reader *. Change for new marking scheme.
(skip_comment): Handle CHILL line comments too. Second
argument is now first character of comment marker; all callers
changed. Issue error for unterminated block comment here.
(cpp_skip_hspace): Recognize CHILL comments.
(copy_rest_of_line): Likewise. Call skip_comment and
parse_string directly, don't go through cpp_get_token. Emit
"/**/" for block comments if -traditional (create_definition
needs this).
(do_define): Don't play with put_out_comments.
(cpp_push_buffer): Initialize ->mark to -1.
(cpp_buf_line_and_col): Just read out the values in the buffer
structure.
(output_line_command): Use cpp_buf_line_and_col. Fix
formatting. Remove stale code.
(cpp_get_token): Break out string parsing code to
parse_string. Use skip_comment for CHILL comments too. Use
copy_comment for put_out_comments instead of dinking with
marks. Remove stale code. Don't call output_line_command
unless it's necessary.
* cpplib.h (parse_marker): Removed.
(struct cpp_buffer): line_base is now a unsigned char *; add
`mark' [long], remove `marks' [struct parse_marker *].
(parse_set_mark, parse_clear_mark, parse_goto_mark): Update
prototypes.
(CPP_BUMP_LINE, CPP_BUMP_BUFFER_LINE): New macros.
* cppinit.c (is_hor_space, is_space): '\r' is not considered
whitespace.
* cppexp.c (cpp_parse_expression): Use cpp_skip_hspace, not
SKIP_WHITE_SPACE.
* cpphash.c (macarg): Disable line commands while expanding.

* cppinit.c: Instead of one pending list, keep separate lists
for each category of pending option: -D/-U, -A, -include,
-imacros. Move the four partial include-path lists into the
pending block. Use head and tail pointers so we don't ever
have to reverse the lists.
(cpp_start_read): Break out blocks of code to their own
functions: install_predefs and initialize_dependency_output.
Use path_include for C_INCLUDE_PATH and friends as well as
CPATH. Remove include_defaults gunk. Warn about the
combination of -lang-chill and -trigraphs. Optimize string
bashing. Walk each pending list once, deallocating as we go.
(append_include_chain): Brought over from cppfiles.c. Mark
dirs as system include dirs if and only if appending to
system include path. If opts->verbose, print a notice when a
dir is dropped from the include path because it doesn't
exist. Fix memory leak: this function is not supposed to copy
its DIR argument.
(nreverse_pending, push_pending): Removed.
(APPEND): New macro for adding to pending lists.
(path_include): Can now add to any partial include path.
(base_name): Bring over from cccp.c.
(cpp_options_init): Allocate the pending block.
(cpp_handle_option): Add --version. Exit after --help. Fix
formatting. Order -ifoo options by frequency of usage.
(install_predefs): New function, simplified version of code
that was in cpp_start_read.
(initialize_dependency_output): Likewise. Understand OBJECT_SUFFIX.
* cppfiles.c (simplify_pathname): Export.
(merge_include_chains): Don't nreverse the lists. If
opts->verbose, print a notice when a duplicate dir is detected
and dropped from the include path.
(finclude): Fix excessive cleverness in setting
fp->system_header_p.
(actual_directory): Set x->sysp from
CPP_BUFFER (pfile)->system_header_p so that one system header
may include another with "".
(deps_output): Fix double adjustment of deps_size which would
cause all dependencies after the first two lines to be lost.
* cpplib.c (cpp_unassert): New function.
* cpplib.h: Lay out struct cpp_pending here. Adjust
prototypes. Add include_prefix_len to struct cpp_options.

* cpphash.c (install): Rename to cpp_install, add cpp_reader*
first argument. All callers changed.
(hashtab): Removed.
(cpp_lookup, cpp_install): Change all refs to hashtab to
pfile->hashtab.
(cpp_hash_cleanup): Removed.
* cpphash.h: Adjust prototypes.
* cpplib.h (struct cpp_reader): Add hashtab pointer.
* cppinit.c (cpp_reader_init): Also allocate space for the
hashtab.
(cpp_cleanup): Delete all macros and free the hashtab.

* cpplib.c: Kill define of STDC_VALUE. Don't include output.h
or prefix.h. Change CPP_IS_MACRO_BUFFER to not refer to
macro_cleanup.

create_definition, compare_defs, comp_def_part, ARG_BASE,
struct argdata, macarg, change_newlines, timestamp,
monthnames, special_symbol, unsafe_chars, macroexpand,
push_macro_expansion): Move to cpphash.c.
(quote_string, check_macro_name, cpp_expand_to_buffer,
output_line_command, cpp_undef): Export.
(null_underflow, null_cleanup, handle_directive): Make static.
* cpplib.h: Prototype now-exported functions. Adjust decls of
syntax tables so we can include cpplib.h in cppinit.c.
* cpphash.h: Prototype all functions exported by cpphash.c.
* cppinit.c: Make syntax tables initialized data if possible
(uses GCC designated-initializer extension).
* cppexp.c: Make cpp_lex static.
* Makefile.in: Move -D switches for the various include dirs
from cpplib.o rule to cppinit.o rule. Adjust dependencies.

assigning to one.
* cppfiles.c (read_and_prescan): Cast the result of `xrealloc' to
U_CHAR* when assigning to one. Ensure the values of a ?: operator
have the same type.
* cppinit.c (initialize_char_syntax): Use K&R function definition.
