I think I may have worked out what is wrong. I understand now (actually
again, I'd forgotten) that the old mingw project is a little bit stale,
and that mingw64 is the way forward.

I'd configured my build using:

$ ../cygwin-setup/configure --host="i686-pc-mingw32" -C

which is using the legacy mingw32 compiler and its stale w32api.

That w32api has a strange guard around the definitions for the above:

#if (_WIN32_WINNT >= 0x0502)
#define KEY_WOW64_64KEY 0x0100
#define KEY_WOW64_32KEY 0x0200
#endif


And however it is defined, _WIN32_WINNT is set as 0x0400.

I am trying with:

$ ../cygwin-setup/configure --host="i686-w64-mingw32" -C

I am expecting this will work. I can report back if necessary.
