I'm basically brain dead when it comes to using configure.in but
according to the texinfo file for autoconf we have the following:

 - Macro: AC_PROG_YACC
     If `bison' is found, set output variable `YACC' to `bison -y'.
     Otherwise, if `byacc' is found, set `YACC' to `byacc'.  Otherwise
     set `YACC' to `yacc'.

So I don't think there should be a problem. To eliminate the warning
message maybe we need to add a check for byacc in configure.in as
follows

AC_PROG_YACC
if test "$YACC" != "bison -y"; then
  if test "$YACC" != "byacc" && test "$YACC" != "yacc"; then
    AC_MSG_WARN(You will need bison/yacc as required for various GRASS
modules.)
  fi

The rest of the code in configure.in checks the version of bison. I
don't know, just guessing.
