Subject: (cpp_options_init): Ignore DOLLARS_IN_IDENTIFIERS.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9e979f8fd8fb1ac8a2402e5c3b9e4f4a51783712;p=gcc.git

(cpp_options_init): Ignore DOLLARS_IN_IDENTIFIERS.

(parse_name): Diagnose $ in identifier if pedantic.
(cpp_handle_options): -traditional no longer messes with dollars_in_ident.
