Most of these functions can be static. A few are unused. * src/coding.c (encode_string_utf_8, decode_string_utf_8): Define only if ENABLE_UTF_8_CONVERTER_TEST, as they're not needed otherwise. * src/coding.c (encode_string_utf_8, decode_string_utf_8): * src/data.c (integer_mod): * src/fns.c (base64_encode_region_1, base64_encode_string_1): * src/ftfont.c (ftfont_get_fc_charset): Now static. * src/sysdep.c (verrprintf): Remove; unused.
