* ptype.pas, read_named_type, array_dec: 
  allow border checks if both range elements are orddefs; for normal arrays
  using e.g. "0..15" this will allow to declare the correct amount of
  elements in the initialization while for generic arrays (e.g. "0..SizeOf(T)") 
  this will mean that only one element can be declared, which was already the 
  case before this change (maybe in such cases a constant initialization should 
  be forbidden in the future...)
+ added test
