Building Emacs (git sources from today) on Cygwin 2.9.0/x86_64:
1. I configured in a subdirectory (VPATH build) with options
     --disable-silent-rules --without-all --without-x
2. "make" succeeds.
3. "make check" leads to a process that is stuck, does not continue
   for several hours. It does not eat much CPU time, but nevertheless,
   something is blocked. Log file 'make-check.log' is attached.
