* bootstrap.conf (gnulib_modules): Add intprops.
* ftp/ftp.c: Include intprops.h.
(portstr): Size buffer to fit exactly 'in_port_t' and a NUL byte.
(hookup): Use 'in_port_t' to represent the port instead of int. Use
sprintf since the buffer size is safe.
* ftp/extern.h (hookup): Adjust deceleration.
* ftp/ftp_var.h: Include netinet/in.h for type definitions.
* ftp/Makefile.am (LDADD): Add $(CLOCK_TIME_LIB).
* ftp/extern.h (struct timespec): Add a forward declaration.
(ptransfer): Use timespec instead of timeval.
(tvsub): Remove declaration.
* ftp/ftp.c: Include <float.h> and <timespec.h>
(sendrequest): Use current_timespec instead of gettimeofday.
(recvrequest): Likewise.
(ptransfer): Use timespec_sub instead of tvsub. Divide by FLT_MIN
instead of 1 if seconds is zero.
(tvsub): Remove function.
* ftp/cmds.c (account, user): Don't declare getpass since it is
defined in unistd.h.
* ftp/ftp.c (login): Likewise. Don't declare fclose and pclose since
they are defined in stdio.h.
* ftpd/extern.h: Don't declare getusershell since it is defined in
unistd.h.
* ftpd/ftpd.c: Don't declare fclose since it is defined in stdio.h.
* libinetutils/logwtmp.c: Don't declare errno since it is defined in
errno.h.
* libtelnet/misc.c (auth_encrypt_user): Include string.h and don't
declare strdup.
* telnet/authenc.c (telnet_gets): Don't declare getpass since it is
defined in unistd.h.
* telnet/commands.c (hostname): Use NULL instead of 0.
(env_init, shell): Include string.h and don't redeclare functions.

Take care to preserve the desired peer's name. Do not
replace it with its canonical name. Bug was reported to
the list as `2015-02/msg00000.html' by John Sullivan.
For a numerical host name, getaddrinfo() need not set
a value for `ai_canonname'. Protect against this.
Problem was uncovered by a system running OpenBSD 5.5.
