I could not find any place in the entire source tree which
Generated a value for NO_READLINE.  I was attempting to
build GHCi with the interactive system on Win32, but because
NO_READLINE was not defined, the build failed expecting
readline to be available.  I see you have a better=20
Understanding of the readline config mechanisms than I do
-- maybe you can suggest the correct way to derive a value
for NO_READLINE in InteractiveUI.hs?
