-dnl as in ISO C99.
-dnl Note that compound literals such as (struct s) { 3, 4 } can be used for
-dnl initialization of stack-allocated variables, but are not constant
-dnl expressions and therefore cannot be used as initializer for global or
-dnl static variables (even though gcc supports this in pre-C99 mode).
