Dear Ralph,

I have asked the user to send me the complete configure script.
Meanwhile, I have uploaded the config.log the user sent me:
you can fetch it from

    http://www.cs.unipr.it/~bagnara/config.log

I don't think I have made any copy and paste error, but maybe
you can spot the cause of the problem.

Yes, because it is in a loop: this is resulting from

AC_CHECK_HEADERS([getopt.h signal.h sys/time.h sys/resource.h sys/time.h 
sys/types.h unistd.h])
