        * macro.c (collect_args): Add pragma_buff argument.  Push
        CPP_PRAGMA ... CPP_PRAGMA_EOL tokens to *pragma_buff, rather
        than into arguments.  Reset prevent_expansion and parsing_args
        state at CPP_PRAGMA_EOL/CPP_EOF.
        (funlike_invocation_p): Add pragma_buff argument, pass it through
        to collect_args.
        (enter_macro_context): Add result argument.  Adjust
        funlike_invocation_p caller.  Emit all deferred pragma tokens
        gathered during collect_args before the expansion, add a padding
        token.  Return 2 instead of 1 if any pragma tokens were prepended.
        (cpp_get_token): If enter_macro_context returns 2, don't return
        a padding token, instead cycle to grab CPP_PRAGMA token.
        * directives.c (_cpp_handle_directive): If was_parsing_args
        in deferred pragma, leave parsing_args and prevent_expansion as is.

        * gcc.dg/cpp/pr34692.c: New test.
        * gcc.dg/gomp/pr34692.c: New test.
