Hi Takashi,
Thank you for posting your steps, they helped me solve this issue.
Everything on my end was similar, except that instead of bash
configure I used a custom script that was supposed to prepare the
environment. On closer inspection, it turned out that the script was
downloading make 4.0 and running bash configure with parameter
MAKE=/path/to/make-4.0. After removing that, the build finished
without any issues. It was also much faster than with
cygwin-3.2/make-4.0.
Thanks again,
Daniel
