Libltdl configure options

[Thomas Degris]

Hello,

I am using libltdl in my project called Satom 
(http://savannah.nongnu.org/projects/satom/). Satom uses automake to 
handle the compilation process. However, I have some troubles 
configuring (with the configure script) Satom with libltdl on mingw. 
When I pass options to configure to set Satom, these options are send to 
the configure script of libltdl that returns an error because it does 
not support these options. For examples, I run:
./configure --prefix=/mingw/apps --enable-debug 
--with-libxml2=/mingw/apps --with-libxslt=/mingw/apps
and I get the following errors:
configure: running /bin/sh './configure' --prefix=/mingw/apps  
'--prefix=/mingw/apps' '--enable-debug' '--with-libxml2=/mingw/apps' 
'--with-libxslt=/mingw/apps' --enable-ltdl-convenience 
--cache-file=/dev/null --srcdir=.
configure: error: invalid feature name: debug
configure: error: /bin/sh './configure' failed for libltdl

So, I would like to know if there is way to remove options before to 
pass them to libltdl. I guess that another solution would to set libltdl 
to ignore unknown features. You can find my current configure.ac at the 
following url:
http://savannah.nongnu.org/cgi-bin/viewcvs/satom/satom/configure.ac?rev=HEAD&content-type=text/vnd.viewcvs-markup

I am using the following versions:
aclocal (GNU automake) 1.7.1
libtoolize (GNU libtool) 1.4e
autoheader (GNU Autoconf) 2.56
automake (GNU automake) 1.7.1
autoconf (GNU Autoconf) 2.56

Thanks for helping,

Thomas
