 * Lexical scanner for SoCalculator. Compile into lexical scanner

 *
 *             flex -oso_eval.ic -L evaluator.l
 *
 * (Note: flex version should be 2.5.4, since this is what is
 * installed on nfs.sim.no).
 *
 * Flex 2.5.4 generates code that includes unitstd.h. unistd.h does
 * not exist on the windows platform. You therefore need to apply
 * a patch after running flex:
 *
 *             patch -p0 < so_eval.diff
