27-autoscan-acheaders.patch

[Akim Demaille]

Index: ChangeLog
from  Akim Demaille  <address@hidden>
        * autoscan.pl (@kinds, %generic_macro): New.
        (&init_tables): Use them.
        * acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
        and include all these headers in here.
        Don't specify `AC_CHECK_HEADERS' as it's the default.
