I really should buy Cloanto's Emulation package someday, so I could revive my
Amiga memories someday ;)

Cool. 

Could you give my tarball on
http://www.kaffe.org/~robilad/kaffe-1.1.x-dt-1.tar.gz a try, and check if that
one doesn't suffer from that problem anymore? Then I could send a patch off to
libtool developers and have it fixed for their next release. ;)

I found the one on line 470, which seems to be an autoconf bug: all AC_SUBST-ed
symbols are output on the same line, instead of breaking up the line in smaller
parts. I'll file a bug with the autoconf team..

I haven'r spotted the one on line 32770 yet, could you elaborate what's on it
so I can grep for it?

that's the best kind of bugs ;)

it should come from libltdl, it's the conveniernce library form of libltdl. See

http://sources.redhat.com/autobook/autobook/autobook_74.html#SEC74 . It builds
libltdlc.la for me on i686-linux as well ;)

yes

hm ... could you post your compressed libltdl/config.log ?

On a side note, given that you've spend the last couple of days finding bug
after bug in current automake/autoconf/libtool implementations, you might
consider subscribing to their mailing lists, getting the latest versions (kaffe
uses automake 1.7.5, autoconf 2.57, and libtool 1.5), building them, running
their regression test suites and posting some bug reports over there as well. I
bet they would appreciate someone taking care of fixing the Amiga port. Given
that more and more tools will make a transition to current versions of auto*
tools, that would be quite healthy for other projects porting GNU-ish software
to the Amiga as well ... especially once the new, fast PPC amigas arrive ;)

cheers,
