(j3.2006) definition of CFI_CDESC_T

[Malcolm Cohen]

(cc'd to interop-tr which is probably a better place for discussion).

That does not look like "a type suitable for declaring a C descriptor" to me.

Surely, given
   CFI_CDESC_T(2) x;
then x must be a C descriptor, and therefore &x must be compatible with 
CFI_cdesc_t*, and x.base_addr et al should be usable; neither of those things 
appear to be true of this (that or my eyes have glazed over too much).

It might be "a type suitable for declaring something [that might be] at least as 
big as a type suitable for declaring a C descriptor", but that is a horse of a 
decidedly different colour, no?

Cheers,

In my ballot on N1911, I expressed interest in seeing implementations of the
function-like macro CFI_CDESC_T.  The definition in my experimental version of
the header ISO_Fortran_binding.h is

#define CFI_CDESC_T(n) struct{long long ____[(sizeof(CFI_cdesc_t)+7)/8+3*(n)];}
