Remove -1 case.

(cpp_notice_from_errno, cpp_ice): New functions.
(cpp_notice): Is now for reporting error conditions, just
without an associated file.
(cpp_error, cpp_error_with_line): Don't do anything if
opts->inhibit_errors is on.
(cpp_pedwarn_with_file_and_line): Take column argument also.
* cpplib.h: Update prototypes of exported functions.
(struct cpp_options): Add inhibit_errors.
* cppalloc.c, cppfiles.c: Use fprintf not cpp_notice for
non-error messages. Include intl.h.
* cppinit.c, cppmain.c: Likewise. Also, use
cpp_notice_from_errno instead of cpp_perror_with_name or
cpp_pfatal_with_name, and cpp_notice instead of cpp_message.
* cppexp.c, cpphash.c, cppinit.c, cpplib.c: Use cpp_ice to
report internal errors.
* cpplib.c (do_define): Switch bcopy to memcpy.
Give cpp_pedwarn_with_file_and_line a dummy column argument.

* cppfiles.c (read_and_prescan) [case SPECCASE_QUESTION]: Bump
input pointer before possibly branching off to the backslash
code.
* cpphash.c (macroexpand): Correctly delete \r escapes when
stringifying parameters.

if we can; bail out early if we hit a line comment.
(handle_directive): Treat '# 123' in an .S file just like
'# <punctuation>'. Discard the shifted '#' if we hit '#\n'.
Return 1 for '# not_a_directive'.
(get_directive_token): Pop macro buffers here, so that
cpp_get_token can't sneakily move past a newline.
Add sanity checks.
(cpp_get_token): goto randomchar if handle_directive returns 0.
From-SVN: r31819
* cpplib.h (cpp_reader): Add new flag, no_directives.

find a directive, issue an error and discard the line.
From-SVN: r31763
* cpperror.c (cpp_file_line_for_message): If 'line' is zero,
just print "<command line>". If 'filename' is null or an
empty string, print "<stdin>" for the filename.
* cpplib.c (do_define): Don't print the 'location of the
previous definition' message if we're still parsing the
command line.
(cpp_pedwarn_with_file_and_line): Always call
cpp_file_line_for_message.
From-SVN: r31697
* cppinit.c (cpp_handle_option): Recognize C++ comments under
-std=gnu89.
* cpplib.c (skip_block_comment, skip_line_comment): Split code
out of...
(skip_comment) ... here. Permit C++ comments in system
headers always. Warn about C++ comments in user code under
-std=gnu89 -pedantic.
(copy_comment): Use skip_comment.
(cpp_skip_hspace, cpp_get_token): skip_comment can no longer
return EOF.
(consider_directive_while_skipping, do_else, do_endif): Call
validate_else unconditionally.
(validate_else): Check CPP_PEDANTIC here. Accept non-comment
text after the conditional in a system header.
* cpplib.h (struct cpp_buffer): Add flag
warned_cplusplus_comments.

* cpplib.h (struct cpp_options): Change lang_asm to char.
Add lang_fortran.
* cppinit.c (builtin_array): Take out __STDC_VERSION__, it's
done in cpp_handle_option now.
(initialize_builtins): Take out special case code used only by
__STDC_VERSION__.
(cpp_handle_option): Turn off trigraphs and trigraph warnings
if -traditional. Recognize -lang-fortran and set
lang_fortran, also turn off cplusplus_comments.
(print_help): Document -lang-fortran.
* cpplib.c (handle_directive): Ignore `# 123 "file"' if
lang_asm. Ignore all directives other than `# 123 "file"' if
CPP_PREPROCESSED.
(cpp_get_token): If -traditional, don't recognize directives
unless the # is in column 1.
(parse_string): If lang_fortran or lang_asm, silently
terminate strings ('' or "") at end of line.
Remove unnecessary braces.
