'Undefined _MAX for xgrass on SunOS4.1.1'

I got an 'Undefined sysmbol' error when I compiled xgrass on SunOS4.1.1.
under grass4.1/source/src/xgrass/menu.  I tries to 'grep _MAX' or 'grep MAX'
over all souce codes under xgrass/menu and all possible include files, but
nothing was found meaningful to me.  Please help.
