You teach me about the -dD option. Nice!

Your copy of gnulib-tests/fcntl.h is more than two months old. It contains
traces of GL_LINK_WARNING, which we are not using any more since 2010-01-20.
At the same time, you are using a test-fcntl-h-c++.cc from a couple of days
ago.
I would recommend to do
1. "make distclean"
2. verify that gnulib-tests/fcntl.h is gone
3. "./configure"
Did you by bad chance run './bootstrap' without a prior "make distclean"?
Or were the timestamps disturbed by git?
