The odepkg I use was installed with an earlier version of octave, before 
the pkg was moved to unmaintained.  It seems to work OK.

I can not rebuild the package with the current version of octave.  Most 
of the problems stem from changes within octave and gcc.  I see
GCC_ATTR_UNUSED undefined
feval needs to be octave::feval
is_xxxxx needs to be isxxxxx for several different functions
   xxxxx = empty, etc.
config.h is included but should not be
some problems in macro expansion for F77_FUNC

Maybe too much to fix, at least for me.  I am unable to maintain the odepkg.
