Problem configuring RTEMS for m68k (Cygwin)

I get a strange crash when configuring RTEMS (rtems-ss-20001121) for target
m68k-rtems on Cygwin host.

When the configure script (rtems-ss-20001121/c/make/configure) checks for
whether the compiler is a cross compiler, it builds conftest.exe and tries
to start it. This should fail since the exe is for 68k. However, Cygwin
hangs after trying to start it.

config.log output:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

My configuration:
- up-to-date Cygwin (1.1.6)
- m68k-rtems-binutils-
- 68k-rtems-gcc-gcc2.95.2newlib1.8.2.tgz
- rtems-base-binutils-
- rtems-base-gcc-gcc2.95.2newlib1.8.2.tgz

Any ideas?
