cygwin32-b20 _tkinter problem

[Monika Göhmann]

When I try to compile python-1.5.2b2 under WinNT with Cygwin32-B20 it
works very well without Tk-Module. But when I try to include Tk, I get
the following messages:

gcc   python.o \

My Modules/Setup looks like this

Tcl/Tk header and libs are in the Cygwin32-directories and the
compiler finds them.

Since I have no idea, what is the equivalent of X11 under Cygwin, I
used libstdc++. Is this the problem ?
