Well, I was about to embark on an effort to mark these particular
functions as EXPORTS in the .def file and release a new readling, but AJ
Reins hinted in another message in this thread that the readline
packaged within bash might be different than the standalone version. 
So, it's probably best to just admit defeat (wrt bash) and require that
cygwin-bash be built using the internal readline library.  And not
modify the export table to accomodate bash.

Comments?
