Bug#417486: [Pkg-octave-devel] Bug#417486: FTBFS with GCC 4.3: missing #includes

[John W. Eaton]

I expect that some 2.9.x version of Octave will be declared the
recommended version of Octave before GCC 4.3 (or maybe even GCC 4.2)
is released, so I don't have any plans to fix these problems in my
2.1.x sources.  You're of course free to fix them in the Debian
packages.

I'd be much more interested in whether Octave 2.9.10 builds cleanly
with GCC 4.2 and 4.3.
