As this pre-processor definition is defined in curl_setup.h there is no
need to include it in the Visual Studio project files.

Removed the WIN64 pre-processor definition from the libcurl project
files as:

* WIN64 is not used in our source code
* The curl projects files don't define it
* It isn't required by or used in the platform SDK
* For backwards compatability curl_setup.h defines WIN32
* The compiler automatically defines _WIN64 for x64 builds

Historically Visual Studio projects have defined WIN32, in addition to
the compiler defined _WIN32 definition, and I had incorrectly changed
that to WIN64 for the x64 libcurl builds but not in the curl projects.

As such, it is questionable whether this should be defined or not. For
more information see the following cache of a discussion that took
place on the microsoft.public.vc.mfc newsgroup:

packages/vms/backup_gnv_curl_src.com: Originally copied from Bash port.

To offer some more info and yet it doesn't use more lines.

... as it requires TLS and it was was left to warn on the default from
when default was SSL...

... as it never copies the trailing zero anyway and always just the four
bytes so let's not mislead anyone into thinking it is actually treated
as a string.

It was initially reported by Guenter that GetFileSizeEx
requires (_WIN32_WINNT >= 0x0500) to be true.

Second patch to enable Windows support using Cygwin-based OpenSSH.

Tested with CopSSH 5.0.0 free edition using an msys shell on Windows 7.

First patch to enable Windows support using Cygwin-based OpenSSH.

Removed 'next' variable in Curl_convert_form(). Rather than setting it
from 'form->next' and using that to set 'form' after the conversion
just use 'form = form->next' instead.

This also removes the need to check that the 'form' argument is valid.

As 'result' isn't used out side the conversion callback code and
previously caused variable shadowing in the libiconv based code.

This also fixes a variable shadowing issue when HAVE_ICONV is defined
as rc was declared for the result code of libiconv based functions.

Verbose output was not matching the actual configuration file,
because FIPS and Windows conditions were ignored.

Recent stunnel versions (5.08) seem to have trouble with relative
paths on Windows. This turns the relative paths into absolute ones.

Fixes SF bug 1149: http://sourceforge.net/p/curl/bugs/1449/

There was a confusion between these: this commit tries to disambiguate them.
- Scope can be computed from the address itself.
- Scope id is scope dependent: it is currently defined as 1-based local
  interface index for link-local scoped addresses, and as a site index(?) for
  (obsolete) site-local addresses. Linux only supports it for link-local
  addresses.
The URL parser properly parses a scope id as an interface index, but stores it
in a field named "scope": confusion. The field has been renamed into "scope_id".
Curl_if2ip() used the scope id as it was a scope. This caused failures
to bind to an interface.
Scope is now computed from the addresses and Curl_if2ip() matches them.
If redundantly specified in the URL, scope id is check for mismatch with
the interface index.

This commit should fix SF bug #1451.

As the former contruct apparently caused a compiler warning, mentioned
in d8efde07.

There was a mix of GlobCode, CURLcode and ints and they were mostly
passing around CURLcode errors. This change makes the functions use only
CURLcode and removes the GlobCode type completely.

The loop in glob_next_url() needs to be done backwards to maintain the
logic. dc197894 caused test 1235 to fail.

Change CURLOPT_TIMEOUT doc to warn that if CURLOPT_TIMEOUT and
CURLOPT_TIMEOUT_MS are both set whichever one is set last is the one
that will be used.

Prior to this change that behavior was only noted in the
CURLOPT_TIMEOUT_MS doc.

Commit b13923f0 changed an snprintf() to use aprintf(), but the API usage
wasn't correct, and was causing a crash to occur. This fixes it.

By counting from 0 and up instead of backwards like before, we remove
the need for the "funny" check of the unsigned variable when decreased
passed zero. Easier to read and less risk for compiler warnings.

The >= 0 is actually not required, since i underflows and
the for-loop is stopped using the < condition, but this
makes the VS2012 compiler and code analysis happy.

Fixes code analysis warning C6031:
return value ignored: <function> could return unexpected value
