+## CYGNUS LOCAL
+## Don't mess with people's installed readline's.
+## This tries to install this version of readline over whatever
+## version is already installed on the system (which could be a
+## newer version). There is no real reason for us to install
+## readline along with GDB. GDB links statically against readline,
+## so it doesn't depend on us installing it on the system.
