commit37bb3cce45suppressed the declaration for C++, where it is wrongly interpreted as declaring the function as taking no arguments. with C23 removing non-prototype declarations, that problem is now also relevant to C. the non-prototype declaration for basename originates with commit06aec8d715, where it was designed to avoid conflicts with programs which declare basename with the GNU signature taking const char *. that change was probably misguided, as it represents not only misaligned expectations with the caller, but also undefined behavior (calling a function that's been declared with the wrong type). we could opt to fix the declaration, but since glibc, with the gratuitously incompatible GNU-basename function, seems to be the only implementation that declares it in string.h, it seems better to just remove the declaration. this provides some warning if applications are being built expecting the GNU behavior but not getting it. if we declared it here, it would only produce a warning if the caller also declares it themselves (rare) or if the caller attempts to pass a const-qualified pointer.
