Hi Greg,

Thanks again for the feedback.

I'm just off for a week of camping and Tae Kwon-do, so I don't have time to
look into these now :-(

I'll postpone the alpha release until these are done, if any intrepid souls would like to send a fix to address@hidden for my return a week on
Monday, I'll put the release out then :-)

Hi Gary,
        I dropped the current libtool CVS head on my fedora box to give is a
go. I found two issues, one easy and one not so easy (at least for me).
        First the easy issue.  I think there's a typo in the last line of
libtool/libltdl/loaders/  In particular in the recursive
invocation of make to build ../

        cd ..; $(MAKE) $(MAKEFLAGS)

I changed $(MAKEFLAGS) to $(AM_MAKEFLAGS).

        For the second issue, the proper fix is less clear to me.  Basically
mdemo fails to link on Fedora because it is missing "-ldl" on the link line, resulting in undefined symbols for dlopen, etc. In libtool-1.5.6, the -ldl seems to come about because it is in dependency_libs in In turn,
it seems to have gotten *there* because it is in dependency_libs in
        However, in the current head release, -ldl does appear in
dependency_libs in loaders/, but it doesn't end up in the
dependency_libs when is built. (So it isn't in, therefor isn't specified in the mdemo link, and the link fails. I guess it isn't clear to me if there's something that needs special-case handling here and I'm not sure I could produce a surgical patch if there is. Any thoughts?
