   "Partially" because the vararrays module merely defines
   __STDC_NO_VLA__ a la C11.  The new module would define
   VLA_ELEMS, which would be the rest of the job that gnulib
   could reasonably do.

IIUC, as it is proposed, RCS would still have to do that test
and then re-‘#define VLA_ELEMS’:

 #if BUGGY
 #undef VLA_ELEMS
 #define VLA_ELEMS(x)
 #endif

I think it would be more useful to expand the scope of module
‘vla’ to do the configure-time test, too, such that RCS can
simply include it and use ‘VLA_ELEMS’ unconditionally.  Buggy
compiler workarounds are under gnulib purview, after all, right?
