We could still ask them, so that this goes away in future releases.

  The code in the header looks like:

  #define	   __HUGE_VAL_bytes    { 0, 0, 0, 0, 0, 0, 0xf0, 0x7f }

  #ifdef	 __GNUC__
  #define	 HUGE_VAL	(__extension__ \
					  ((__huge_val_t) { __c: __HUGE_VAL_bytes }).__d)
  #else		  /* Not GCC.  */
  static __huge_val_t __huge_val = { __HUGE_VAL_bytes };
  #define		    HUGE_VAL   (__huge_val.__d)
  #endif		    /* GCC.  */

We'd like to fall into the /* Not GCC */ case, at least #if
__cplusplus, if we don't undo my change.
