readline problems linking octave binary - Cygwin 1.3.5/Win2K

[Sujay Parekh]

I'd appreciate any help with building the latest (2.1.35) Octave under Windows.  I'm using Windows 2000 with the latest Cygwin (dll version 1.3.5-3).  I ran it as everyone else seems to be doing: "configure" then "make" (with no additional options).

Thing seem to go ok, until it gets to linking the octave binary, at which point I get an error:

/usr/local/src/octave-2.1.35/liboctave/oct-rl-edit.c:63: undefined reference to 
`_rl_clear_screen'
collect2: ld returned 1 exit status

I looked in /usr/lib/libreadline.a for this '_rl_clear_screen', and it seems to be there:
{76} nm -o /usr/lib/libreadline.a | grep -i _rl_clear_screen
/usr/lib/libreadline.a:readline.o:         U __rl_clear_screen
/usr/lib/libreadline.a:readline.o:00001544 T _rl_clear_screen
/usr/lib/libreadline.a:funmap.o:         U _rl_clear_screen
/usr/lib/libreadline.a:keymaps.o:         U _rl_clear_screen
/usr/lib/libreadline.a:display.o:0000249c T __rl_clear_screen

Other than that extra "-rdynamic" flag to c++, the only other warning I saw in the make has to do with something in the kpathsea build -- the c-proto.h there redefines "__cdecl", but it is only a warning and in any case I don't know if it is relevant to the readline problem.

I am able to build fine if I use 'configure --disable-readline', so it seems specific to the readline support or libs.
