The two options seams to work, --enable-shared and --with-pic.  I am
asking what is the best option in the opinion of Xorp developers, as I
am one of the persons building xorp to be released in Debian.  But
this weekend I had to use a i386 machine for the tests.  It don't
break the compilation but complains about non -fPIC code inside a
shared library.

Now that my x86_64 machine is again working I can try it and be 100%
certain that --enable-shared or --with-pic solve the problem.

I am using release 1.5 with some updates from CVS.
