The debugging code in linux-waitpid.c is one of the few remaining spots that depends on the gdb/gdbserver difference. My first thought was that this code is not extremely useful, so this patch removes this code. (However, if it is actually useful to someone, we could make it work by introducing a new abstraction.) gdb/ChangeLog 2019-06-11 Tom Tromey <tom@tromey.com> * nat/linux-waitpid.c: Don't include server.h. (linux_debug): Remove. (my_waitpid): Update.
