+All these directory variables have values that start with either
+@code{$@{prefix@}} or @code{$@{exec_prefix@}} unexpanded.  This works
+fine in @file{Makefiles}, but it makes these variables hard to use in
+@file{configure}.  This is mandated by the GNU conding standard, so

+Variables, autoconf, The Autoconf Manual}).
