BZ closed wontfix.
Thoughts?

--- Comment #4 from Michael Matz <ma...@su...> ---
Yes, this works as designed, and indeed -dumpversion can be (and is) used
for path composition.  If you compare filelists and -dumpversion output of
different gcc compilers you'll see that paths in opensuse packages use
the version differentiator as returned by -dumpversion, _not_ as in the output
of --version, this is the same on debian (and I think fedora).  It's just
that some packagers included the microversion in it and we don't.

With the version scheme change of GCC 5 the microversion went away, basically
shifting all number positions one up, so now we don't include the minor version
anymore in directory paths, and hence also not in -dumpversion, so in the
future
it'll only be a single number.  Read http://gcc.gnu.org/develop.html#num_scheme
for a little background on the changed versioning scheme.

Yes, this upstream change causes some hassle in packages trying to parse the
version, that's unfortunate but was to be expected.
