In the C code the function wl_display_connect has the following signature:

I don't think it's GNAT specific. This is implementation advice in ARM B.3. But 
I would recommend using the types in Interfaces.C whenever possible when 
interfacing with C. In this case, that would be Interfaces.C.char_array.

When there is no suitable type in Interfaces.C, I recommend only using types 
that have been declared with convention C.
