Reported by Eric Blake at <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>. * bootstrap.conf (gnulib_modules): Add unsetenv. * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add. * m4/.gitignore, m4/.cvsignore (/environ.m4): Add. (/setenv.m4): Add. * src/output.c (output_skeleton): For the m4 invocation, pass -dV as the first argument because it may become position-dependent, and unset POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions. Add comments explaining these issues in more detail.
