BTW, next month I plan to release a new patch that will not use
internal libtiff structures access (requires some additions to libtiff
API, which are settling). This should resolve build and compatibility
problems as yours.

Looks like different optimizations are used for the libImaging library
and for the Python extension itself.  Try checking CFLAGS in libImaging/
Makefile.win and the options setup.py uses to compile decode.c
