(do_include): Diagnose #import and #include_next if pedantic and if
not in a system header.
(do_warning): #warning now causes an error if -pedantic-errors is
given; this is needed since #warning isn't ANSI.
From-SVN: r13887
(unsafe_chars): `p' is unsafe before `-' or `+', since it
might generate a C9X-style hexadecimal floating-point number.
(cpp_handle_options): Set c89 option to 1 if -lang-c89.
From-SVN: r13749
(macroexpand): Delete any no-reexpansion marker that follows an
identifier at the beginning of an argument that is concatenated with
what precedes it.
From-SVN: r13356
* cpplib.c (xcalloc): From from cppalloc.c.
* cpplib.c (cpp_push_buffer): If recursion too deap, return NULL
rather than exiting with fatal.
(make_assertion, cpp_expand_to_buffer, push_macro_expansion,
do_include, cpp_start_rea): Handle NULL return from cpp_push_buffer.
(output_line_command): Update position even if no_output.
(parse_clear_mark): Use fatal instead of abort.
From-SVN: r12207
* cpplib.c (init_parse_option): Renamed to cpp_options_init.
(push_parse_file): Renamed to ...
(cpp_start_read): Change to return 1 on success, 0 on failure.
(init_parse_file): Renamed to cpp_reader_init.
* cpplib.c (cpp_start_read, cpp_handle_options, cpp_finish,
parse_goto_mark, parse_move_mark): Use cpp_fatal rather than fatal.
* cpplib.c (newline_fix): Remove unused function.
From-SVN: r12202
* cpplib.h, cpplib.c: Remove support for !STATIC_BUFFERS.
* cpplib.c (special_symbol, do_once, do_include, cpp_get_token):
Compare cpp_buffer against CPP_NULL_BUFFER, not NULL.
* cpplib.c (dump_special_to_buffer): New function.
(initialize_builtins): Use it.
From-SVN: r12170
* cpplib.c (line_for_error): Make it work; add extra parameter.
(skip_quoted_string, cpp_get_token): Update calls to line_for_error.
(macroexpand): Remember initial line so we can report it if the
call is unterminated. Also, simplify error logic slightly.
(do_include): Cast alloca return value, to avoid pcc warning.
From-SVN: r9635
* cpplib.c: Rename make_definition to cpp_define.
* cpplib.c (special_symbol): For T_SPECLINE, calculate __LINE__
in enclosing file buffer, not current buffer (if macro expanding).
(cpp_get_token): Fix thinko (in code for chopping unneeded space).
From-SVN: r9403
* cpplib.c (SELF_DIR_DUMMY): New macro.
(do_include): Don't pass searchptr to finclude if it is dsp,
since that is on the stack, and would cause a dangling pointer.
If handling #include_next, recognize SELF_DIR_DUMMY.
From-SVN: r9320
