bug#66289: localeinfo.c:33:39: error: macro "static_assert" requires 2 arguments, but only 1 given

I was trying to build GNU grep on a NetBSD 9.3 machine when I saw this
nasty bit of business :

Seems odd given :

/usr/include/assert.h:112: note: macro "static_assert" defined here
  112 | #define static_assert(x, y) __CTASSERT(x)
      |

Maybe I need some prerequisite somewhere ?
