Re: modules poll* fail on mingw-w64 for i686 and x86_64

[Hannes Müller]

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:
