cppinit.c (cpp_handle_option): Recognize C++ comments under -std=gnu89.
* 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.
