Actually this was the problem I was trying to resolve, but I couldn't
replicate it for a while due to another issue, likely due to the
0.11.2 cython install as you indicated.
The failure to compile issue occurs for both MS visual studio 2008 and
the free version of that compiler.
The way to coerce MS Visual Studio to show the includes is apparently
with the /P option, which puts them in the source file. (So save a
copy of the source if you need it).
Anyway here is how the macro is defined and embedded into test.c, for
the prior test.pyx example I provided:
> #ifndef CYTHON_PROFILE
> #define CYTHON_PROFILE 1
> #endif
This part is in the #if CYTHON_PROFILE section.

Oh and then there are some other special cases it seems:
#if CYTHON_PROFILE
#include "compile.h"
#include "frameobject.h"
#include "traceback.h"
...
...
#else
#define __Pyx_TraceCall(funcname, srcfile, firstlineno)
#define __Pyx_TraceException()
#define __Pyx_TraceReturn(result)
#endif /* CYTHON_PROFILE */
So the change could well be related to how CYTHON_PROFILE is being handled.
