Description:
wcwidth(3) used in readline code is implicitly declared when building
on Linux due to the fact that _XOPEN_SOURCE is not defined. Currently
only Solaris builds define this.

How to repeat:
Compile. Inspect warnings.

Suggested fix:
Either define _XOPEN_SOURCE for Linux in the same manner as for
Solaris (include/my_global.h), or optionally determine with configure
which platforms can/should have XOPEN compatibility defined.
