/* Each of these macros verifies that its argument R is nonzero.  To
   be portable, R should be an integer constant expression.  Unlike
   assert (R), there is no run-time overhead.

If _Static_assert works, verify (R) uses it directly.  Similarly,
   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
   that is an operand of sizeof.

The code below uses several ideas for C++ compilers, and for C
   compilers that do not support _Static_assert:

* The first step is ((R) ? 1 : -1).  Given an expression R, of
     integral or boolean or floating-point type, this yields an
     expression of integral type, whose value is later verified to be
     constant and nonnegative.

* Next this expression W is wrapped in a type
     struct _gl_verify_type {
       unsigned int _gl_verify_error_if_negative: W;
     }.
     If W is negative, this yields a compile-time error.  No compiler can
     deal with a bit-field of negative size.

One might think that an array size check would have the same
     effect, that is, that the type struct { unsigned int dummy[W]; }
     would work as well.  However, inside a function, some compilers
     (such as C++ compilers and GNU C) allow local parameters and
     variables inside array size expressions.  With these compilers,
     an array size check would not properly diagnose this misuse of
     the verify macro:

void function (int n) { verify (n < 0); }

* For the verify macro, the struct _gl_verify_type will need to
     somehow be embedded into a declaration.  To be portable, this
     declaration must declare an object, a constant, a function, or a
     typedef name.  If the declared entity uses the type directly,
     such as in

struct dummy {...};
       typedef struct {...} dummy;
       extern struct {...} *dummy;
       extern void dummy (struct {...} *);
       extern struct {...} *dummy (void);

two uses of the verify macro would yield colliding declarations
     if the entity names are not disambiguated.  A workaround is to
     attach the current line number to the entity name:

#define _GL_CONCAT0(x, y) x##y
       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
       extern struct {...} * _GL_CONCAT (dummy, __LINE__);

But this has the problem that two invocations of verify from
     within the same macro would collide, since the __LINE__ value
     would be the same for both invocations.  (The GCC __COUNTER__
     macro solves this problem, but is not portable.)

A solution is to use the sizeof operator.  It yields a number,
     getting rid of the identity of the type.  Declarations like

extern int dummy [sizeof (struct {...})];
       extern void dummy (int [sizeof (struct {...})]);
       extern int (*dummy (void)) [sizeof (struct {...})];

can be repeated.

* Should the implementation use a named struct or an unnamed struct?
     Which of the following alternatives can be used?

extern int dummy [sizeof (struct {...})];
       extern int dummy [sizeof (struct _gl_verify_type {...})];
       extern void dummy (int [sizeof (struct {...})]);
       extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
       extern int (*dummy (void)) [sizeof (struct {...})];
       extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];

In the second and sixth case, the struct type is exported to the
     outer scope; two such declarations therefore collide.  GCC warns
     about the first, third, and fourth cases.  So the only remaining
     possibility is the fifth case:

extern int (*dummy (void)) [sizeof (struct {...})];

* GCC warns about duplicate declarations of the dummy function if
     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
     __COUNTER__ macro that can let us generate unique identifiers for
     each dummy function, to suppress this warning.

* This implementation exploits the fact that older versions of GCC,
     which do not support _Static_assert, also do not warn about the
     last declaration mentioned above.

* GCC warns if -Wnested-externs is enabled and verify() is used
     within a function body; but inside a function, you can always
     arrange to use verify_expr() instead.

* In C++, any struct definition inside sizeof is invalid.
     Use a template type to work around the problem.  */
