script to fail on debian unstable (some specific bash version perhaps?)

AC_CHECK_HEADERS() and the action-if-found since that action is run even if
just one of the six headers is found and I just now fell over a case with
a duplicate file name (a krb4 implementation with an err.h file).

I converted the check to manually make sure three of the headers are present
before considering them fine.

arguments work properly - and the option is not harmful for the rest of the
curl build either!

instead of LDFLAGS.

not supporting it. It hasn't been functioning for years anyway, so this is
just finally stating what already was true. And a cleanup at the same time.

done in one single function CURL_CHECK_FUNC_GETNAMEINFO which
will only define HAVE_GETNAMEINFO if the function has been found
AND the type of its arguments has been properly been detected

CURL_FUNC_GETNAMEINFO_ARGTYPES now also checks first argument.
All related changes taken to cares configuration scripts.

valid windows.h winsock.h winsock2.h and ws2tcpip.h
header files:
CURL_CHECK_HEADER_WINDOWS
CURL_CHECK_HEADER_WINSOCK
CURL_CHECK_HEADER_WINSOCK2
CURL_CHECK_HEADER_WS2TCPIP

Determine the correct type to be passed to four of the `getnameinfo' function's arguments, and define those types in `GETNAMEINFO_TYPE_ARG2', `GETNAMEINFO_TYPE_ARG46', and `GETNAMEINFO_TYPE_ARG7'.

don't have one in order to fix a remaining warning on IRIX 6.2.

http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
connection closure so we check for that case (too) and re-enable poll for
cygwin builds.

right: http://curl.haxx.se/mail/archive-2005-11/0045.html so we now disable
poll() and use select() on cygwin too (we already do the same choice on Mac OS
X)

version of libcurl with different Windows versions. Current version of
libcurl imports SSPI functions from secur32.dll. However, under Windows NT
4.0 these functions are located in security.dll, under Windows 9x - in
secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
just forwards calls to secur32.dll).

Dmitry's patch loads proper library dynamically depending on Windows
version. Function InitSecurityInterface() is used to obtain pointers to all
of SSPI function in one structure.

to a warning message as a first step. We should persue to make curl use
c-ares properly even when built with ipv6 support.
