Since glibc-2.43:
For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return pointers
into their input arrays now have definitions as macros that return a
pointer to a const-qualified type when the input argument is a pointer
to a const-qualified type.
fixes:
src/openvpn/dns.c: In function 'dns_server_addr_parse':
src/openvpn/dns.c:67:25: warning: initialization discards 'const' qualifier
from pointer target type [-Wdiscarded-qualifiers]
67 | char *first_colon = strchr(addr, ':');
| ^~~~~~
src/openvpn/dns.c:68:24: warning: initialization discards 'const' qualifier
from pointer target type [-Wdiscarded-qualifiers]
68 | char *last_colon = strrchr(addr, ':');
| ^~~~~~~
