 The GCC library should not contain any messages that need
 internationalization, because it operates below the internationalization
 library.

 Unlike some other GNU programs, the GCC sources contain few instances

 By convention, any function parameter in the GCC sources whose name
 ends in `msgid' is expected to be a message requiring translation.
-For example, the `error' function's first parameter is named `msgid'.
+If the parameter name ends with `gmsgid', it is assumed to be a GCC

+For example, the `error' function's first parameter is named `gmsgid'.
 GCC's exgettext script uses this convention to determine which
 function parameter strings need to be translated.  The exgettext
 script also assumes that any occurrence of `%eMSGID}' on a source
 line, where MSGID does not contain `%' or `}', corresponds to a
 message MSGID that requires translation; this is needed to identify
 diagnostics in GCC spec strings.
+The `G_(GMSGID)' macro defined in intl.h can be used to mark GCC diagnostics
+format strings as requiring translation, but other than that it is a
