no code generation for c strings

[Luke A. Guest <laguest@archeia.com>]

Hi,

In my current binding efforts I'm having to have a bunch of c strings which
denote the function name that needs to be requested from the API. If I
create an Ada string and convert it to c then whole application gets two
copies of each string which is overkill.

What I would like to have is have the compiler recognise that I've declared
a static char_array and just not generate a call to the secondary stack to
allocate a new string. Is this actually possible? -O2/3 still generate the
call.

S : constant char_array := to_c ("hello" & nul);
