Hi Bruno,

You introduced rl_readline_state_t in the following commit:

description:
readline: Update binding to avoid build failure with GNU readline 7.0.

I'm now getting errors like the following for several of the modules I 
build:

This is on Cygwin.  I don't currently have access to a Linux system on 
which I can build clisp, so I don't know if the problem is Cygwin-specific.

My knowledge of how modules work is very limited, but shouldn't the 
typedef of rl_readline_state_t have been propagated to some header used 
in building other modules that rely on readline?
