Hi Bruno, 

Thanks for your reply. Sorry, now the output with correct line breaks.
For the following test command I got the below noted output on mingw-
w64 with latest gnulib from git repository.

./gnulib-tool --create-testdir --dir=/tmp/testdir poll poll-tests poll-
h poll-h-tests
cd /tmp/testdir
./configure && make




Result for i686:
