But crtdefs.h says:<br>
<br>
<font face="Courier New, Courier, monospace">#ifdef _WIN64<br>
typedef unsigned __int64 size_t;<br>
#else<br>
typedef _W64 unsigned int size_t;<br>
#endif<br>
</font><br>
Which conflicts with the built-in definition, that seems to be
equivalent to:<br>
<br>
<font face="Courier New, Courier, monospace">typedef unsigned int
size_t;</font><br>
<br>
What determines the built-in type of size_t? Is there some setting
or variable I can define to change it?<br>
<br>

Later on, I get an error saying that crtdefs.h is trying
to redefine size_t from an unsigned int to an unsigned
long long...<br>
<br>
Perhaps one of my preprocessor defines is causing these
errors:<br>
<br>
<font face="Courier New, Courier, monospace">WIN32<br>
_DEBUG<br>
_WINDOWS<br>
_USRDLL<br>
_SCL_SECURE_NO_WARNINGS<br>
_CRT_SECURE_NO_WARNINGS<br>
_WIN64<br>
_x86_64_ = 1<br>
</font><br>
(I added the "SECURE_NO_WARNINGS" defines when I ported an
earlier version of this code to VS 2005; don't remember
why any more...)<br>
(There are a couple of other defines that are specific to
the DLL I'm trying to build)<br>

I just verified that the LLVM-vs2013 toolset.props

If it is a bitness problem, perhaps I'm failing to

<div>I recall that you copied the win32 platform

think they will have the correct flags. If you
see this line in the x64 toolset.props file,
replace -m32 with -m64 and try again:</div>

Looking at the preprocessor expansion of a
typical .cpp file, I see that crtdefs.h
defines size_t like this:<br>
<br>
<font face="Courier New, Courier,
monospace">typedef unisgned __int64
size_t;<br>

Later on,
<LLVM>\lib\clang\3.6.0\includes\stddef.h
defines it as:<br>
<br>
<font face="Courier New, Courier,

</font><br>
Is there some other magic I need to do to
get these to work?<br>
<br>
I'm also seeing a bunch of errors like
this having to do with intrinsics:<br>

I suspect that these might be caused by
the same thing as the size_t problem...<br>
