Can you provide a patch? To do so, create a testdir

  ./gnulib-tool --create-testdir --dir=../testdir-ulc1 --single-configure \
                 unistdio/ulc-fprintf unistdio/ulc-asprintf 
unistdio/ulc-snprintf \
                 unistdio/ulc-vasnprintf unistdio/ulc-vfprintf

Build it, run "make check", and add '|| strcmp ...' alternatives until the
tests pass.

Can you do this please? I can't, since for me (with MSVC 14 = Visual Studio 2015
on Windows 10), the tests pass.
