I've identified that this patch causes problem for me in GSS, when
running autoreconf I get this error message:
Copying file po/en@quot.header
Copying file po/insert-header.sin

See the Autoconf documentation.

However if I remove the following from all gnulib-common.m4 (there are
three of them):

Then building works fine.
Any ideas why this happens?
Note that I am NOT calling gl_ASSERT_NO_GNULIB_POSIXCHECK or doing
anything related to posixcheck as far as I know.
Reproduce by:
git clone git://git.sv.gnu.org/gss.git
cd gss
make
