Digital Mars - c++ - compiler bug?

Hello.

Here is a snippet of the code I am compiling(part of a commercial package):

template<class T>
class Vector
{
   protected:
    U32 mElementCount;
    U32 mArraySize;
    T*  mArray;

    bool  resize(U32);
   public:
    Vector(const U32 initialSize = 0);
    Vector(const U32 initialSize, const char* fileName, const U32 lineNum);
    Vector(const char* fileName, const U32 lineNum);
    Vector(const Vector&);
    ~Vector();

    typedef T        value_type;
    typedef T&       reference;
    typedef const T& const_reference;

    typedef T*       iterator;
    typedef const T* const_iterator;
    typedef S32    difference_type;
    typedef U32    size_type;

...

    void insert(iterator, const T&);
    void erase(iterator);

...
    void push_front(const T&);
    void push_back(const T&);
    void pop_front();
    void pop_back();
...
};


z:/torque/engine\core/tVector.h(102) : Error: type qualifiers and static 
can only appear in outermost array of function parameter

z:/torque/engine\core/tVector.h(110) : Error: type qualifiers and static 
can only appear in outermost array of function parameter

z:/torque/engine\core/tVector.h(111) : Error: type qualifiers and static 
can only appear in outermost array of function parameter

line 102 is at the insert() function
line 110 is the push_front()
line 111 is the push_back()

What am I missing here?  This library compiles fine with gcc, 
metrowerks, and visual c++.

Thanks.

Hello Walter.

First thanks for the great compiler(and the quick response).

The package I am compiling is Torque (www.garagegames.com).
Since it is fairly tight-coupled(house of cards!) I have reproduced what 
is the jist of the problem(see code below).

When you attempt to insert a static array as a template parameter it 
says no.  This seems a reasonable error to me but gcc compiles it.

I also tried to typedef ('block' type below), but that doesn't work either.

Since I am in essence porting this engine to your compiler, I could make 
some changes, but I wanted your thought on it.


Thanks again,
David Medlock


// begin code snippet

template<class T>class Vector
{
   public:
   void insert(T*, const T&) {;}
};


typedef unsigned int U32;
typedef unsigned int block[50];

int main( int argc, char** argv )
{
         Vector<U32[50]> int_vector;
	Vector<block>	int_block_vector;
}

Cool!

Btw. not to pile anything else on you, but this also gives issues:


int a = 0;
if ( bool(a) ) a++;

is the C++ cast of bool(x) valid?

Thanks again,
David Medlock
