Depends what you aim at. If you want a really portable program without
configuration, you apparently can't use these functions (recent
Solaris also has them).  If not, I don't see any reason not to use
them.  They are simple enough, so it should be trivial to include in
any application.

I don't think you should put too much effort into a mass conversion
project. The problem with this is that you are quite likely to get it
wrong in many places, like the

        strcpy(foo, bar) -> strlcpy(foo, bar, sizeof(foo))=20

conversion for `char *foo'. There are places where the strncpy
behaviour is really used, even if they are not that common.
