[bug-inetutils] syntax-checks

[Simon Josefsson]

I have fixed so that gnulib's 'make syntax-check' works again, and by
running it I noticed these three complaints:

1) We use HAVE_CONFIG_H a lot:

maint.mk: found use of HAVE_CONFIG_H; remove
make: *** [sc_prohibit_have_config_h] Fel 1

Any objections to dropping all HAVE_CONFIG_H uses in InetUtils?  GNU
projects appears to be moving away from it, and there is no point for
any project using gnulib (like InetUtils) to use HAVE_CONFIG_H since
gnulib code already assumes there is a config.h.

2) Internationalization issues:

ftp/main.c
ftpd/ftpd.c
ifconfig/ifconfig.c
libinetutils/argcv.c
ping/ping.c
ping/ping6.c
src/hostname.c
src/inetd.c
src/logger.c
src/rcp.c
src/rexec.c
src/rexecd.c
src/rlogin.c
src/rlogind.c
src/rsh.c
src/rshd.c
src/syslogd.c
src/tftp.c
src/tftpd.c
src/traceroute.c
src/uucpd.c
talk/talk.c
talkd/talkd.c
telnet/main.c
telnetd/telnetd.c
tests/addrpeek.c
tests/localhost.c
maint.mk: the above files do not call bindtextdomain

With the exception of the programs in tests/, it looks like this
indicate a real bug: that there aren't any translations.  InetUtils
should be internationalized.  We don't even have any po/ directory!  I'm
assuming this is an oversight?

Marking strings has to be done manually and carefully to make sure we
translate useful strings.  It would quite an effort to resolve this in
one go, however we can start on this and add strings as we move along.

Any objections to creating a gettext domain for InetUtils and start
marking strings for translation?

3) There is an error:

prohibit_always_true_header_tests
/bin/bash: line 0: cd: ./gnulib/lib: No such file or directory
0.03 prohibit_always_true_header_tests

I'm not sure if this indicates a gnulib or Inetutils problem, but it
seems this particular test is not ran properly.
