Then this comment in gengtype.c becomes no longer valid, and confusing:
/* Record the definition of a generic VEC structure, as if we had expanded
the macros in vec.h:
> typedef struct VEC_<type>_base GTY(()) {
> unsigned num;
> unsigned alloc;
> - <type> GTY((length ("%h.num"))) vec[1];
> + <type> GTY((length ("%h.prefix.num"))) vec[1];
> } VEC_<type>_base
>
> where the GTY(()) tags are only present if is_scalar is _false_. */
In vec.h:
> +#ifndef GTY
> +#define GTY(x) /* nothing - marker for gengtype */
> +#endif
It could be fixed by changing the #include order in vec.c:
#include "system.h"
+#include "coretypes.h"
#include "ggc.h"
#include "vec.h"
-#include "coretypes.h"
#include "diagnostic-core.h"
#include "hashtab.h"
