Since I regenerated my configure scripts with 2.62, I started to see
warnings:
configure: " --with-libffcall-prefix
CLISP configuration consists of the main configure script for the core
lisp system, as well as a separate configure script for (almost) each
module.
The configure is invoked like this:
./configure --with-module=pcre --with-libpcre-prefix=/usr/local
- --with-module=postgresql --with-libpq-prefix=/usr/db --with-module=foo
- --with-module=bar

the sub-configure scripts are called with all the --with-lib*-prefix
arguments because the top-level script cannot determine which
sub-configure needs which argument, so each of
        modules/pcre/configure
        modules/postgresql/configure
        modules/foo/configure
        modules/bar/configure
is called with arguments
        --with-libpcre-prefix=/usr/local --with-module=postgresql
which results in many warnings:
WARNING: Unrecognized options:

Is there a way to avoid the warnings?
I am worried that eventually the warnings will mutate into errors - are
there any plans like that?

thanks.
