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.

* 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).

** TO BE PORTED BACK TO 2.71 **
As pointed out by Thomas Beck (plasmasolutions), the current behaviour and/or
default values for their parameters didn't quite make sense:
1) Back Easing - The old default value of 0.0 results in some overshoot being applied,
while trying to tweak it up or down resulted in some odd jumps and discontinities.
I've ended up removing some code here which forcibly using a "back" value of 1.7
when users wanted 0.0 instead. There doesn't seem to be any good reason for this.
To ensure that there is still an effect initially, keyframes now get created
with back set to 1.7
2) Elastic Easing - The old default settings of <amplitude = 0, period = 0> resulted
in a curve without any elastic bounce, which wasn't very useful for motion graphics.
Now, default values of amplitude = 0.8 and period = 4.1 get set. These were hand picked
by Thomas to work well when the duration of the motion is 10 frames long (i.e. the
typical length of such effects when doing motion graphics).
Simple search for intersections became slow for larger concave ngons (100+)
Tested to work with ngons up to 75k sides, performance is approx ~6x faster then scanfill.
This is a 2D version of BLI_kdtree with modifications:
- nodes can be removed
- an index -> node map is stored (especially for tessellation)
Issue was caused by _wstat returning EOVERFLOW error because
of file size didn't fit into stat structure which was using
long datatype.
The idea of this patch is to use _wstat64 and _stat64 structure
which is capable storing 64bit file sizes.
Made it a typedef for stat structure used by BLI_stat function
in order to make code easier to follow and avoid ifdefs all
over the place.
Additionally solved issue with BLI_exists which was wrongly
returning False in cases destination file is larger then 4GB.
It still warns the user that there may be an error, but the baking goes
on. Also using the new is_uniform_scaled_m4() instead of float comparison.
Reported and fix suggested by Campbell Barton as a concern over 2bfc3deb
On windows "." was replaced with the root directory.
On other systems any path starting with a '.' would be replaced with "/"
This was added for the file selector only,
so better handle this in the file selector (though it looks not to be needed).
Undoing nodes that do not belong to the current object will cause the
saved bmesh log entry to be reverted instead. This entry can belong to
another object though.
This is easy to fix by enforcing name matching (this was borrowed by
edit mode but can definitely be improved) between current object name
and undo node name and deleting older entries.
However there are complications. Deleting dyntopo entries in this way
can leave a brush stroke as first dyntopo log entry. This can present
issues if we attempt to delete that entry since it's deleted mesh
elements may now have had their ids (which would still be valid at the
time) cleaned up. This can result in crashing if we attempt to resculpt
on the mesh. To fix this I have disabled releasing the deleted entries.
This entanglement between bm_log and undo is quite volatile but I hope
the system works better now.
Also minor cleanup, fix unneeded check warning
