* 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. From-SVN: r31654
