Darryl L. Miles 932deeaf2d readline: define _XOPEN_SOURCE at the top of files 
It is a requirement to define feature_test_macros(7) as soon as possible
before including any files, otherwise the headers may not allow further
configuration, as reconfiguration maybe denied.  You need to pick the
standard you wish to work with for the compilation unit (the file).

This can be seen with an error for lack of symbol `wcwidth()` from wchar.h

Moving the order slightly fixes the compile failure issue.
See feature_test_macros(7) for more info.

README 

The readline/ directory contains the source for GNU readline-4.3. We
are keeping a copy of the library in the readline/ directory to keep
the magic distribution self-contained.
