- bug fix in lax parameter parsing (it may happens that wrong values are

computed/introduced under Redhat 9)
- bug fix in xsch driver : the VST driver may add intermediate signals
  and loon has no idea of those signals after driving the resulting optimized
  netlist. Loon then displayed the message -> "signal foo not found in hash table"
  and stopped. Now it adds those signals in its internal hash table, and there is
  no longer error.
