No, the fix is

#ifdef HAVE_FLEXIBLE_ARRAY_MEMBERS
  decl_t decls[];
#else
  decl_t decls[1];
#endif

Where

/* 1 if we have C99 flexible array members.  */
#if !defined(HAVE_DESIGNATED_INITIALIZERS)
#define HAVE_DESIGNATED_INITIALIZERS \
  ((GCC_VERSION >= XXX) || (__STDC_VERSION__ >= 199901L))
#endif

where XXX ought to be looked up; 3.2 or 3.3 is probably right.
