On some distros, i.e. rhel 7.6, compilation fails with the following:
ipaddress.c: In function ‘lookup_flag_data_by_name’:
ipaddress.c:1260:2: error: ‘for’ loop initial declarations are only allowed in C99 mode
for (int i = 0; i < ARRAY_SIZE(ifa_flag_data); ++i) {
^
ipaddress.c:1260:2: note: use option -std=c99 or -std=gnu99 to compile your code
This commit fixes the single place needed for compilation to pass.
Fixes: 9d59c86e575b ("iproute2: ip addr: Organize flag properties structurally")
