Details:

I have a current installation of Cygwin x64 (dll version 1.7.25), with the
latest Octave package (3.6.4)  installed. I wanted to use the expfit function
from the optim package in octave-forge, so I the following from the Octave
prompt:

pkg install -forge optim

After working through the dependencies, optim installed (albeit with some
warnings about unusable help text and optimset: no defaults).

expfit remains undefined.

I noticed that in my home directory the octave-forge packages were in a folder
called octave, and that ~/octave/optim-1.2.2/expfit.m existed. However, in
/usr/share/octave/3.6.4/m/optimization/ only the following existed:

__all_opts__.m  fminbnd.m  fsolve.m  glpk.m       optimget.m  PKG_ADD     
private  sqp.m
expfit.m        fminunc.m  fzero.m   lsqnonneg.m  optimset.m  pqpnonneg.m 
qp.m

Manually copying ~/octave/optim-1.2.2/expfit.m to
/usr/share/octave/3.6.4/m/optimization/ resolved the problem and I could then
run expfit from octave.

Why are only some of the optim packages actually installed in the octave
package directory?

I tried the same procedure on Cygwin x86. In that case an octave-forge package
is available. It installs optim-1.2.2 as well, but again the layout is like
so:

/usr/share/octave/packages/optim-1.2.2/ contains expfit.m and friends

/usr/share/octave/3.6.4/m/optimization/ does not, only containing the same
subset as in the x64 case.
