That's a good question. In theory, we could annotate these functions
with __attribute__((__deprecated__)):

https://gcc.gnu.org/onlinedocs/gcc-3.3.4/gcc/Type-Attributes.html

But I'm actually too afraid to use it. In the worst case it may cause
the compiler to generate a warning even when basename()/dirname() is
used correctly, as __old_* will still be part of the compiled
expression.
