Fix quoting

Give third argument to AC_DEFINE_UNQUOTED

Use native type SOCKET instead of int when testing functionality of ioctlsocket on Windows

Ooops

Fixed compiler warning on libc5.

Add checking for type DWORD as argument 4 and 6 of getnameinfo

Adjust more windows header includes

Fixed lcc compiler warnings.

Fix guard detection of _WIN32_WINNT for MingW in CURL_FUNC_GETNAMEINFO_ARGTYPES

Add check for 'unsigned int' as type of arguments 4 and 6 of getnameinfo

Undo previous change. This header file belongs to the public
interface and the change could break the compilation of thrid
party apps which link against this library.

When checking the type of the first argument of getnameinfo do it in the
following order: 'struct sockaddr *' 'const struct sockaddr *' 'void *'.

Fix spacing. When defining, define to 1.

Cleanup windows header includes. Where aplicable, inclusion of
windows.h winsock.h winsock2.h ws2tcpip.h is done in setup.h

MingW guards getnameinfo, getaddrinfo and freeaddrinfo with _WIN32_WINNT >= 0x0501

Fix Msys/Mingw not detecting getnameinfo() with AC_CHECK_FUNCS

Make it compatible with vc60 and vc71

Fix typo

Fix compiler warning

Cleanup

Windows related cleanup

Check first arg of getnameinfo with and without const qualifier.

Change multiple header inclusion prevention definition to __LIB_CURL_SETUP_H

Avoid breaking configure due to CURL_FUNC_GETNAMEINFO_ARGTYPES failure, since at this point nothing depends on it.

const qualifier in getnameinfo check
