I don't think so.  The "_" define typically marks the string for translation,
but it doesn't add the information this is a format string using
"gcc-internal-format" rather than regular printf() style formatting.  According
to comment 3, that can be achieved by using the define "G_" rather than plain
"_" for those strings using "%L" or any other GCC specific formatting
directives..
