This isn’t a comment “against” this patch, but something I’ve been wondering
recently and which raises a question about how to handle strcpy’s deprecation
in particular. There is still one scenario where strcpy is useful: when GCC
replaces it with its builtin, inline version...
Would it be worth introducing a macro for strcpy-from-constant-string, which
would check that GCC’s builtin is being used (when building with GCC), and
fall back to strscpy otherwise?
Regards,
Stephen
