I think the older gcc is wrong; we are switching on "method & 3", which must be in the range 0-3 (and we cover all cases). I do not mind silencing the warning anyway, but see this discussion: http://thread.gmane.org/gmane.comp.version-control.git/258186 The thread seems very broken in gmane, but it continues here: http://article.gmane.org/gmane.comp.version-control.git/258232 http://thread.gmane.org/gmane.comp.version-control.git/258245 http://article.gmane.org/gmane.comp.version-control.git/258264 -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
