This is a minor cleanup I spotted whilst working on another patch. No functional change intended. Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu. Pushed to trunk as r15-1900-g113b5ce0610207. gcc/c-family/ChangeLog: * c-format.cc (format_check_results::format_check_results): New ctor. (struct format_check_context): Add ctor; add "m_" prefix to all fields. (check_format_info): Use above ctors. (check_format_arg): Update for "m_" prefix to format_check_context.
