configure checked for library functions with LIBS instead of
LIBS_server, which could break detection of getaddrinfo() on systems
where LIB_SOCKET isn't empty.
GNUmakefile put @PTHREAD_LIBS@ only in LDLIBS, which breaks linking of
server and possibly client on systems where it is not empty.
Broken in commit 8b778634.
Make configure compute three sets of libraries: LIBS_client for the
client, LIBS_server for the server, and LIBS for the rest. This
replaces termlibs.
Unfortunately, LIBS doesn't work with Windows, because
src/lib/w32/posixio.c pulls in socket stuff. Temporary workaround:
use LIBS_server instead.
Checking Windows libraries with autoconf is cumbersome, because
linking often fails unless you include the header, and AC_SEARCH_LIBS
doesn't permit that.
Just detect the Windows API instead, with new MY_WINDOWS_API.
getpass() is traditional Unix, but has been withdrawn from POSIX. As
such, it may be missing. Check for that, and provide ersatz. It's
not a real replacement, because it doesn't do the special magic
getpass() is supposed to do: read from /dev/tty without echo.
This bypasses our existing getpass() for Windows. In contrast to the
portable getpass(), the Windows one tries to turn off echo, but that
doesn't work for me (MinGW & Wine). Remove it.
Detect .git instead of CVS. Use git-ls-files with git, else
$(srcdir)/sources.mk. info/findsubj.pl now gets the info files as
arguments rather than from sources.mk.
Remaking info subjects doesn't quite work, but it was broken similarly
before.
order-only prerequisites. They were used to make directories
info.html, info.nr, lib. Make them ahead of time, in configure. Also
fixes distclean not removing them.
(tcp_listen, player_addrlen): New. IPv4-only code factored out of
player_init().
(player_init): Use them.
(player_accept): Address family independence.
(tcp_connect): New.
(main): Use it.
(hostaddr, hostconnect, hostport): Internal linkage.
