fixed-0.7.10.tar.gz with octave-3.2.2

I cannot compile fixed-0.7.10.tar.gz package on octave-3.2.2

When I build the fixed package from within the octave-forge SVN and with
the tip of the 3.2.x tree under a debian x86 system, with

cd main/fixed/src
./configure
make

I don't see any build issues. So I then tried with the 3.2.3-RC1 and
fixed-0.7.10.tar.gz with

pkg install fixed-0.7.10.tar.gz

within Octave and also didn't see this problem. Not being able to
reproduce this problem I don't see how I can fix it. Note that I had no
other packages installed when installing the fixed package.

That's really weird, because looking at the code, it should fail
AFAIK. Array<T> should be always instantiated using the
INSTANTIATE_ARRAY macro (which overrides
Array<T>::instantiation_guard). This was done because implicit
instantiations of Array<T> should basically never happen, so that we
want to guard against them.

Replacing the template statements by INSTANTIATE_ARRAY should fix the
problem. I'll patch it later if you won't do it sooner.

Ok I undetstand my 0.7.10 was built from the SVN with a patch form the
13 June.. The last release of octave-forge was 8 June and so the
difference is the instantiation.. So this seems to already be patched..
The next release of octave-forge will fix this issue.
