Hi

I recently installed Cygwin 1.3.2 on a Windows2000 box.
I then downloaded the Octave 2.0.16 sources and
tried to compile. It fails with the following error:
c++  -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -I../glob
-I../glob -D

The compiler is 
$ c++ -v
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/specs
gcc version 2.95.3-5 (cygwin special)

It seems that it recognizes the option --rdynamic (note two -).
That does however not solve the undefined reference problems.

Is this a known problem with a known solution?
