There's a better solution that doesn't involve waiting a year, and
deprecation, and so forth (problems that gnulib is supposed to avoid).
We just change the name of the unprefixed function.  Its name already
reflects that; it is called "base_name" because it means something
different from the standard "basename".

So I propose that we simply change the name of "base_name" to
"gbasename" (or whatever other name you like), and do something
similar with the other functions.
