Putting the hack in common-defs.h instead worked for me. It has
the advantage of being in the sources, so won't get lost by
a clean rebuild, which regenerates that file.
However, we should instead do what the error says, and report the
issue to bug-gnulib@gnu.org, fix the issue there, and then
pull in a newer gnulib. Maybe the issue is already fixed there
even. That last time we tried pulling in a newer gnulib we
stumbled on a windows.h conflict that will be to resolved
first though. :-/
Thanks,
