I would say, rather, newer GCC defaulting to point out errors in old
code.

int strncasecmp();

has never been compatible with

int strncasecmp(const char *, const char *);

but gcc has had a long-standing (mis)feature whereby the prototype
declaration silently overrides the old-style declaration, thereby
letting people get away with such mismatches.  C23 has, though, done
away with old-style declarations entirely.
