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. -- Ed Schouten <ed@nuxi.nl> Nuxi, 's-Hertogenbosch, the Netherlands KvK-nr.: 62051717
