BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.
No need for separator text.

It's more useful to git-blame to find out who has developed the code.

The Issue
=======
For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.
Why Remove
==========
One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch
If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.
For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3
Fixes T51301

* Fixed different not-in-sync #ifdef blocks for struct stat variants under Windows.
Comments have been left to indicate the portions of BLI_fileops.h and
BLI_fileops_types.h that need to stay in sync.
* Added BLI_wstat() to de-duplicate #ifdef blocks for stat() variants on Windows.
* Fix for opendir() and associate functions in MinGW not working properly with
non-ASCII, MBCS-compatible paths.
MinGW (FREE_WINDOWS) has opendir() and _wopendir(), and only the
latter accepts a path name of wchar_t type. Rather than messing up with
extra #ifdef's here and there, Blender's own implementations of opendir()
and related functions are used to properly support paths with non-ASCII,
MBCS-compatible characters.
Tested with MSVC 2013 Express, MinGW32 (gcc 4.6.2) and MinGW-w64 (gcc 4.7.1).

Some int/float conversion warnings were disabled by buildsystems but
re-enabled by BLI_winstuff.h, the warnigns relate to conversions not
considered issues on other systems so better just quiet them.
The reason of this is because PATH_MAX is not guaranteed
to be defined on all platforms and Hurd doesn't define it.
So either we need to support arbitrary long file path or
we need to define own maximum path length.
The rule here would be:
- If it's not big trouble to support arbitrary long paths
(i.e. in ghost by using std::string instead of char*)
then arbitrary long path shall be implemented.
- For other cases to use PATH_MAX please include BLI_fileops.h
which takes care of making sure PATH_MAX is defined.
Additional change: get rid of own changes made yesterday
which were supposed to make storage.c work fine in cases
PATH_MAX is not define, but on the second though it lead
to unneeded complication of the code.
Thanks Campbell for review!

Other builds may also work but due to the constantly changing nature of the compiler this cannot be guaranteed. I often had to change compilers while building the libraries and this one is the one that did the job for most of them.
This first support is experimental and considered "advanced". To enable pass -DWITH_MINGW64 during cmake configuration. Also make sure to extract the compiler on C:/MinGW and that MinGW/bin is in your path. To build check out lib/mingw64.
Initially the support is lacking until I get every library compiled correctly. For now you should disable WITH_CYCLES(sorry, I know some people are dying to do benchmarks, but still a few libs to go), WITH_IMAGE_OPENEXR, WITH_OPENCOLLADA, WITH_LIBMV and WITH_CODEC_FFMPEG(links but hangs on startup).
Still the tools are working, the memory limit is increased and due to the experimental nature of the setup, full optimization with SSE2 is available, which makes the build quite fast. Also the compiler and especially, the linker are way faster than regular MinGW.
The wiki docs have also updated. Happy testing!
Not all file formats/calls are supported yet. It will be expended.
Please from now on use BLI_fopen, BLI_* for file manipulations.
For non-windows systems BLI_fopen just calls fopen.
For Windows, the utf-8 string is translated to utf-16 string in order to call UTF version of the function.

Fix [#26938] Blender Zoom not working after startup (Windows)
Reported by Ilija Boshkov
by applying patch [#26881] Fix for console disappearing in debug mode [Windows]
Submitted by Alexander Kuznetsov (AlexK)
The patch moves console toggling code into GHOST and improves on the toggling behaviour.
The patch changes handling of WM_SYSCOMMAND so that alt-key toggling isn't a problem anymore.
submitted by Tom Edwards
This patch introduces a switch -con and its longer version --start-console. When giving this on cmd-line you'll get the black console window. The new behaviour is to hide it by default. We'll still see briefly the console at startup and during exit, but that's something that cannot be changed.
If you start blender from a cmd.exe, the console will not be hidden.

Fix [#25473] 64bit Windows installer for version 2.56 is not working
patch submitted by Caleb (Dobz)
The thumbnail patch adds a thumb handler DLL that adds .blend thumbnail support in Windows Explorer. A -r option is added to do registration in background. The patch also improves icon building and metadata for blender.exe.
Caleb fixes and cleans up our installer to an acceptable state. The patch uses the new -r option to do the .blend extension and thumbnailer registration.
Thanks to both Caleb and Tom for their efforts!
Define WINVER=0x0501 for MinGW due to some stuff requres this winver, but
MinGW's default is 0x0400 (thanks AlexKu for point)
Better to replace all #include <windows.h> with #include "BLI_winstuff.h" to
avoid possibility of different functions prototypes in different modules.
* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!
DONE:
* moved almost all declarations from BLI_blenlib.h into their own proper header files.
* BLI_blenlib.h still includes all the declarations for convenience and to avoid changes in existing code
* split util.c into several files, where it wasn't done already
* DynamicList -> dynamiclist,
* ListBase -> listbase,
* String utility functions -> string.c
* removed a few unused macros and functions, if they're needed back, they're still in svn ;)
TODO:
* btempdir global
* further cleanup in the code of the different modules (especially util.c)
