sync from gnulib for install-sh, vasnprintf.c, getaddrinfo, socklen

[Paul Eggert]

I installed this patch to sync from gnulib.

2006-02-14  Paul Eggert  <address@hidden>

        * build-aux/install-sh: Update from gnulib.
        * lib/vasnprintf.c (VASNPRINTF): Rewrite the computation so that we
        need not use xsum.

2006-02-14  Bruno Haible  <address@hidden>

        Sync from gnulib.

        * lib/vasnprintf.c (VASNPRINTF): In the computation of the size of the
        temporary buffer for sprintf, take into account the precision also
        for 'd', 'i', 'u', 'o', 'x', 'X'.

2006-02-14  Simon Josefsson  <address@hidden>

        Sync from gnulib.

        * lib/getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set,
        for mingw32.

        * lib/gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for
        mingw32).

        * m4/getaddrinfo.m4: Look for getaddrinfo inside ws2tcip.h and
        -lws2_32.  Protect sys/socket.h and netdb.h #include's.  Include
        ws2tcpip.h with WINVER=0x0501.  All for mingw32.
        * m4/socklen.m4: Look in ws2tcpip.h too, for mingw32.

 dnl Check for socklen_t: historically on BSD it is an int, and in
 dnl POSIX 1g it is a type of its own, but some platforms use different
 dnl types for the argument to getsockopt, getpeername, etc.  So we
 dnl have to test to find something that will work.
+
+dnl On mingw32, socklen_t is in ws2tcpip.h ('int'), so we try to find
+dnl it there first.  That file is included by gnulib's socket_.h, which
+dnl all users of this module should include.
