This is my point!  My understanding is...
With plain old new, you have a choice of constructors to call
T* = new T            - call the default constructor
T* = new T( const T& )     - call the copy constructor

and if we were using djgpp(2.02) gcc 2.8.1 we could do the same with new[]
T* = new T[n]        - call the default constructor for each member of the
array
T* = new T[n]( const T& )     - call the copy constructor for each member of
the array (***)

however with djgpp egcs 1.1.2 the line marked (***) causes an error iff T is
a built in type.
Why the discrepancy - does one of the djgpp compilers have a bug?  (Note
relevance to djgpp Nate :-)
