Follow-up Comment #1:

I do not see these warnings. What version of GCC and what options are you
building with?

I build with GCC 5.3, with -flto in all of CFLAGS, CXXFLAGS, FFLAGS, and
LDFLAGS, and with AR=gcc-ar, NM=gcc-nm, and RANLIB=gcc-ranlib. The only
warnings I see are about the common sections "ls0001" and "sls001" declared in
ODEPACK.

Moreover, your suggested change looks like it uses Fortran 2003 features. We
try to stick to basic Fortran 77 for all sources in liboctave.

If you can propose a patch that avoids changing the Fortran in such a way, and
hopefully also doesn't require doing casts between std::complex and C99
__complex__, please do. Marking as more info, if you want to try building
again or work on this and provide a different patch.
