Fedora 22 also only has Octave 3.8.  This means that users of the image
package can do the following:

0 - install image package via yum (recommended)
0 - install the image release 2.2.2 via pkg (why would they do this?)
0 - build octave 4.0 from source and install the image package via pkg

Only the third case will be affected by this bug. And if they are building
octave from source, they should be capable enough to apply this simple patch
themselves.

Users of all other release-type distros seems to be unaffected.
Rolling-release type of distros will get the gcc fix soon too. So this bug
will only affect users of Fedora 22. And Fedora has a short release-cycle and
hopefully Fedora 23 will have the gcc bug fixed.

The following will hopefully catch the eye of anyone that ends here and save
them the trouble of reading the whole thing.

* HOW TO FIX THIS WITH GCC 5.1 *

This issue is caused by gcc bug 65843
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65843>. To workaround this
issue, open the image package tarball, and remove the word "const" from lines
154 and 213 of "src/imreconstruct.cc"
