c-common.c (UNGETC [USE_CPPLIB=1]): Do nothing if c is EOF.
1999-02-15 16:59 -0500 Zack Weinberg <zack@midnite.ec.rhno.columbia.edu>
* c-common.c (UNGETC [USE_CPPLIB=1]): Do nothing if c is EOF.
* c-lex.c: Likewise.
* cpplib.c (cpp_push_buffer, cpp_pop_buffer): Use a linked
list in malloced memory for the buffer stack.
(cpp_get_token): Don't pop the last buffer off the stack.
Calls after CPP_EOF has been returned produce CPP_EOF with no
state change.
(cpp_finish): Pop last buffer here.
(do_line): Don't free ip->last_nominal_fname if it is equal to
ip->fname.
(special_symbol): If a T_CONST is the empty string, push a
single `@ ' escape instead.
(macroexpand): Special symbol buffers have escapes too.
* cpplib.h (struct cpp_buffer): Remove unused fields, add prev
buffer pointer.
(struct cpp_reader): Remove buffer_stack. Add
buffer_stack_depth.
(CPP_PREV_BUFFER, CPP_NULL_BUFFER): Buffer stack is now a
linked list.
