Yeah, as I was writing this message, it started looking like maybe that

This seems to have been the problem. I am using out of source builds, 
but until I did a complete copy of the source dir, even starting a new 
place to build in, I still got the wxMac error. Something must be jammed 
up inside the real source directory.

I didn't even have to unmount anything. Copying the source (without any 
CMake stuff other than CMakeLists.txt files) did the job.

Hm, I hadn't heard of this. I think I'm going to move to an old copy of 
visual studio and see if that fixes my weirdnesses that were causing me 
to want to compile without WIN32 (the current one is just too big to run 
on my laptop under parallels). After thinking about it a bit, I'm using 
some prebuilt stuff and some that I compiled with MSYS and MingW. I am 
pretty sure that this sort of mishmash is a recipe for disaster, without 
the WIN32 being defined.
