RE: FYI: duplicate removal patch [Was Re: ok, new libtool for cyg winupdates]

[Robert Boehne]

After installing the attached patch (simply reverts the changes
to ltmain.in) my project is building better, but not quite right.
For some reason, this patch removes all redundant dependency libs
except for -lm.  In the 10th library built (deplibs from 9 others)
there are about a hundred -lm options in the lib*.la file.
Does anyone know why it won't remove "-lm" but removes others
just fine?

Robert
