Message 261534 - Python tracker
IMO this is a fault of the autowhatever configuration stuff, not just an enhancement. If configure.ac determines that there is no st_blocks field, it tries to link against a non-existant fileblocks.o file:
./mingw/Makefile:220:LIBOBJS= ${LIBOBJDIR}fileblocks$U.o
i486-mingw32-gcc: error: Python/fileblocks.o: No such file or directory
I am not really an autoconf or whatever expert, but it seems if you use a lower-level bit of configure.ac code it avoids the problem; see avoid-fileblocks.patch.
