Mph.  I don't actually believe that, nor do I believe the #define
BUILDING_DLL you put in, because neither of those are needed in any of
our contrib modules.  What I suspect at this point is that the reference
to CurrentMemoryContext in the palloc() macro is being bollixed by
having the wrong value for BUILDING_DLL.  However, not having a Windows
build environment to experiment with, I'll have to defer to somebody
with more experience in that.

(I wonder BTW if we should rename BUILDING_DLL, because it seems a bit
misnamed.  AIUI it's supposed to be set while building the core backend,
not while building loadable modules.)
