Don't know when this sneaked in, I did wrote that part of the patch on win VM with MSVC2013... :/
Note: letting asside warnings for now, then should not prevent building anyway.
Current temporary data of Blender suffers one major issue - default 'temp' dir on Windows is never
automatically cleaned up, and can end being quite big when used by Blender, especially when we have
to store per-process data (using getpid() in file names).
To address this, this patch:
* Divides tempdir paths in two, one for 'base' temp dir (the same as previous unique tempdir path),
the other is a mkdtemp-generated sub-dir, specific to each Blender instance.
* Only uses base tempdir when we need some shallow persistance accross Blender sessions - and we always
reuse the same filename (quit.blend...) or generate small file (crash reports...).
* Uses temp sub-dir for heavy files like pointcache or renderEXRs (Save Buffer option).
* Erases temp sub-dir on quit or crash.
To get this working it also adds a working 'recursive delete' to BLI_delete() under Windows.
Note that, as in current code, the 'recover render result' hack-feature that was possible
with SaveBuffer option is still removed. A real renderresult cache feature will be added
soon, though.

compressed files we were not passing the full wide char path to zlib, so not
all file names worked. Now we use gzopen_w available in new zlib versions.
Patch by Tamito Kajiyama, I added an extra check for the zlib version so it
keeps compiling with older versions for now.
For platform maintainers:
Part of this commit are zlib 1.2.8 libraries for windows 32 bit. We still
need update libraries for windows 64 bit and mingw. There's a readme.txt
and build.bat included with instructions on how to build.
from Lawrence D'Oliveiro (ldo)
Get rid of BLI_splitdirstring, replace with calls to BLI_split_dirfile, BLI_split_dir_part and BLI_split_file_part as appropriate.
now blenlib/BLI doesn't depend on any blenkern/BKE functions,
there are still some bad level includes but these are only to access G.background and the blender version define.

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!
