+ - autogen.sh: Prefere automake 1.11 over other releases because this is the
+ last release supporting "de-ANSI-fication" using the included ansi2knr tool.
+ And becuase we _want_ to support old K&R platforms, we try hard to use this
+ release of automake when available to generate our build system.
+ Note: This is only relevant for you if you are building from Git sources.
