A flag to use C89 is obviously bad if you're using features from a later
standard.
I was suggesting that you could pass gcc -std=gnu99 or -std= c99 (I would
go whole hog to C11)

 $ gcc -v --help |& grep std=.*' C '
  -std=c11                    Conform to the ISO 2011 C standard
  -std=c89                    Conform to the ISO 1990 C standard
  -std=c90                    Conform to the ISO 1990 C standard
  -std=c99                    Conform to the ISO 1999 C standard
  -std=gnu11                  Conform to the ISO 2011 C standard with GNU
  -std=gnu89                  Conform to the ISO 1990 C standard with GNU
  -std=gnu90                  Conform to the ISO 1990 C standard with GNU
  -std=gnu99                  Conform to the ISO 1999 C standard with GNU
  -std=iso9899:1990           Conform to the ISO 1990 C standard
  -std=iso9899:199409         Conform to the ISO 1990 C standard as amended
in
  -std=iso9899:1999           Conform to the ISO 1999 C standard
  -std=iso9899:2011           Conform to the ISO 2011 C standard
