+Subject: [PATCH] mk: rework gcc version detection to permit versions newer
+ than 4.x
+
+Upstream-Status: Backport [2.1.0]
+
+Separately comparing major and minor versions becomes seriously clumsy
+when with major version changes, convert the entire version string into
+a numeric value (ie 4.6.0 becomes 460 and 5.0.0 becomes 500) and use
+that for comparisons, eliminate unnecessary negations while at it.
+This makes the comparisons simpler, more obvious and makes gcc 5.0
+naturally recognized at least as capable as newest 4.x.
+
+This three-digit scheme would run into trouble if gcc ever went to
+two-digit version segments, but that hasn't happened in the last 10+
+years so it seems like a safe assumption.
