Cool, good to hear that Kiyo's dosumentation finds its happy readers.

Please take a look at FAQ.embedded for a list of things you can do to reduce
kaffe's size on an embedded platform.

this should be fixed in the current CVS sources.

That's yet another bug in libtool, AFAIK. It seems to pick up libraries passed
by --with-libraries only after it has tried to find a library in common library
locations like /usr/lib. See
http://mail.gnu.org/archive/html/libtool/2001-10/msg00127.html for a possible
patch, that apparently has a typo somewhere ... sigh.

Please report it as a bug to the libtool project, their web site is
http://www.gnu.org/software/libtool/ and point them to the patch.

cheers,
