Using string concatenation with a macro is not appropriate in a message argument to a diagnostic function, because it means the full string (which has to be host-independent) doesn't get extracted for translation. HOST_WIDE_INT_PRINT_* are printf formats for the host printf function (for example, they might use %I64d on Windows host), and are not generally understood by the diagnostic.cc machinery at all; functions using the GCC diagnostic machinery need to use GCC diagnostic formats (which are independent of the host printf function), such as %wd/%wu. -- Joseph S.
