* Remove CPP_PLACEMARKERsneil2000-11-111-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | * cppexp.c (lex): Don't handle CPP_PLACEMARKER. * cpplex.c (_cpp_lex_token): Rename skip_newlines to next_bol * cpplib.c (skip_rest_of_line, check_eol, cpp_push_buffer): Similarly. * cpplib.h: Remove CPP_PLACEMARKER. (struct lexer_state): Rename skip_newlines to next_bol. * cppmacro.c (stringify_arg): Don't handle CPP_PLACEMARKER. Simplify prev_white handling as a result.

(enter_macro_context): Return 2 to indicate an empty macro. (replace_args): Don't bother pre-expanding an empty argument. Handle placemarkers and ## extension during pre-expansion.
