glibc 2.42 has const-preserving functions.
This leads to warnings when there is a const argument
and an assignment to a non-const variable.
Example with GCC 16.0.1 and glibc 2.43 on Fedora Rawhide (F45).
/examples/ipsec-secgw/parser.c: In function ‘parse_ipv4_addr’:
../examples/ipsec-secgw/parser.c:53:13:
warning: assignment discards ‘const’ qualifier from pointer target type
[-Wdiscarded-qualifiers]
53 | pch = strchr(token, '/');
