New, from fileutils 4.0.37. * configure.in: Require Autoconf 2.49c. I took some time before making this decision. This is the only way out for portability issues in Bison, it would mean way too much duplicate effort to import in Bison features implemented in 2.49c since 2.13. AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
