* sysdeps/generic/lockfile.c: Include <stdio.h> (_IO_flockfile, _IO_funlockfile, _IO_ftrylockfile): #undef these in case <libio.h> defined them. (__flockfile, __funlockfile, __ftrylockfile): Functions renamed from __internal_*. (flockfile, _IO_flockfile, funlockfile, _IO_funlockfile, ftrylockfile, _IO_ftrylockfile): Fix aliases accordingly.
