Given that the dynamic linker has no notion of dates or minor version
numbers, it would only have a clear reason to choose the ``newer''
library if its SONAME were different, i.e., if it had a different
major version number. But we shouldn't change the major version
number every time we make a change in libgcc, otherwise the number of
versions of libgcc needed to run a collection of programs will
eventually be of the same order of magnitude as the number of
programs.
