I'm having a problem with the standard new[] operator

The following code (a simple example) compiles and works fine with the
djgpp(2.02) port of gcc 2.81, and with egcs under Redhat Linux 5.2, but
causes an error when I try to use egcs 1.1.2 for djgpp or pgcc for linux

int main( void ) {
 int* x = new int[5](0);
}

The error message I get is:
request for member `__ct' in `*{anon}', which is of non-aggregate type `int'
and obviously the compiler is going to get stuck if it's trying to find
members of a built in type

What is also interesting is the fact that compiling the statement T* x = new
T[n]( const T& ) never causes any problems unless T is a builtin type.

My application of this code is in a template class where not all the types
that the template is instantiated for have a default constructor, so I need
to provide a default object of type T to the new operator.

I have a number of questions:
Does anyone know why this won't compile under egcs for djgpp while gcc
appears to be happy?
Am I using the wrong libraries or headers? or perhaps I need a different
version of the compiler?
Is this standard c++?  If it isn't, then how should I tackle my problem in a
standard compatible manner?

Thanks heaps - any help will be much appreciated
