Subject: [Bug c/101446] -Wpedantic causes an error with zero size array

--- Comment #7 from İsmail Dönmez <ismail at i10z dot com> ---
Well, it's even more confusing, grepping through glibc build log:

../include/stdlib.h:297:8: warning: ISO C forbids zero-size array 'msg'
[-Wpedantic]
  297 | char msg[0];
      |        ^~~


../inet/netinet/ip6.h:92:21: warning: ISO C forbids zero-size array
'ip6r0_addr' [-Wpedantic]
  92 |     struct in6_addr ip6r0_addr[0];
     |                     ^~~~~~~~~~

So even the zero-size array warning behaves differently.
