../../work/libcpp/lex.c:593:18: error: typedef 'check_count' locally defined
but not used [-Werror=unused-local-typedefs]
typedef char check_count[(N == 2 || N == 4) * 2 - 1];
AFAICT check_count is indeed unused and removing the line allows bootstrap to
complete. This has probably been exposed by r187757.
