--- Comment #2 from Jürgen Reuter <juergen.reuter at desy dot de> --- (In reply to Eric Gallager from comment #1) > This should probably handled by upstream libtool Indeed I reported this to libtool as well, and I was not the first apparently. How do you include this? In our code there is a libtool.m4, and then all configures are generated via autoreconf from there. This seems more complicated for the build system of gcc/g++/gfortran.
