Thanks, i looked after that, but unfortunately the readline module in
gnulib is very minimalistic:

Quoted from readline.c:
"This module is intended to be used when the application only need
 the readline interface.  If you need more functions from the
 readline library, it is recommended to require the readline library
 (or improve this module) rather than #if-protect part of your
 application (doing so would add assumptions of this module into
 your application)."

In principle the VL_LIB_READLINE macro from http://autoconf-archive.cryp.to/ 
is what i need, with the exeption that it doesn't make configure fail when 
readline isn't present on the system. I guess i have to modify this
macro to satisfy my needs ...
