I see in configure.in:

AC_CHECK_PROGS(YACC, ['bison -y'])

if test "$YACC"; then
if $YACC --version | sed q | $AWK '{ if ($4 < 1.875) exit 0; else exit 1;}'; then
AC_MSG_WARN([
*** If you are going to modify the grammar files or build from CVS, the installed
*** version of Bison is too old. Bison version 1.875 or later is required.])
fi
fi

Looks documented to me.
