It was too tempting - since the structure of config.status stayed the same
for 14 years.

Thanks, I applying this simpler patch:


2006-12-16  Bruno Haible  <address@hidden>

        Make it work with autoconf > 2.61.
        * Makefile.am (TESTS_ENVIRONMENT): Also set GLIBC2.
        * gettext-3: Use GLIBC2 from the environment instead of grepping
        config.status.
        * gettext-5: Likewise.
        * gettext-6: Likewise.
        * gettext-7: Likewise.
        Reported by Ralf Wildenhues.
