cpplib.h (struct cpp_options): Change lang_asm to char.
2000-01-11 16:24 -0800 Zack Weinberg <zack@wolery.cumb.org>
* 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.
