           Summary: ImportC: Array -> Pointer implicit conversion does not
                    work
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1

In C a value of array type can be implicitly converted to a pointer to it's
first element. This does not work in ImportC.

Example:

---
char* strcpy(char* destination, const char* source);
int puts(char*);

int main()
{
    char staticArray[256];
    strcpy(staticArray, "mhh is allergic to pollen");
    puts(staticArray); 
} 
---
yields:

static_array.c(8): Error: function `static_array.strcpy(char* destination,
const(char*) source)` is not callable using argument types `(char[256], char*)`
static_array.c(8):        cannot pass argument `staticArray` of type
`char[256]` to parameter `char* destination`
static_array.c(9): Error: function `static_array.puts(char*)` is not callable
using argument types `(char[256])`
static_array.c(9):        cannot pass argument `staticArray` of type
`char[256]` to parameter `char*`

Luckily .ptr works fine...
