* cpplib.c (my_strerror, cpp_error, cpp_error_with_line, cpp_error_from_errno, cpp_warning, cpp_warning_with_line, cpp_pedwarn, cpp_pedwarn_with_line, cpp_pedwarn_with_file_and_line): Move to cpperror.c. (cpp_print_file_and_line, v_cpp_error, v_cpp_warning, v_cpp_error_with_line, v_cpp_warning_with_line, cpp_message_from_errno, cpp_perror_with_name): Delete. * cpperror.c (cpp_print_containing_files): Take starting buffer as argument. (cpp_file_line_for_message): Rename to cpp_print_file_and_line. (v_cpp_message): Now called directly by all entry points. Remove -1 case. (cpp_pfatal_with_name, cpp_message): Delete. (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. From-SVN: r31829
