Can't get mkoctfile to run under Cygwin

[Steve Goncalo]

I can get Octave to compile and run under cygwin (1.3.2-1 w/ gcc 2.95.3-5),
but I can not get the mkoctfile command to build the hello.cc example. I've
tried with both the 2.0.16 "stable" build and with 2.1.34 and got similar
results. I put a "set -x" command in the mkoctfile script and convinced
myself I was compiling OK and the problem was in the link.

internally, the script is linking with the command:
c++ -shared -o hello.oct hello.o

I tried adding -L/usr/local/lib/octave and -l's with the three libs in that
area, but that only made matters worse.

Am I doing something wrong, or is the .oct interface broken under Cygwin?

$ mkoctfile hello.cc

... two or three screens of similar undefined references follow.
