+	A new implementation of bc and dc has been imorted in r362681. This
+	implementation corrects non-conformant behavior of the previous bc
+	and adds GNU bc compatible options. It offers a number of extensions,
+	is much faster on large values, and has support for message catalogs
+	(a number of languages are already supported, contributions of further
+	languages welcome). The option WITHOUT_GH_BC can be used to build the
+	world with the previous versions of bc and dc.
