This bug is present in 3.3.3 tarballs (Python-3.3.3.tar.bz2, Python-3.3.3.tar.xz, Python-3.3.3.tgz). This bug is absent in 3.3.2 tarballs.

In unpacked 3.3.2:

$ ./configure
...
$ make Include/Python-ast.h
make: 'Include/Python-ast.h' is up to date.
$ make Python/Python-ast.c
make: 'Python/Python-ast.c' is up to date.


In unpacked 3.3.3:

$ ./configure
...
$ make Include/Python-ast.h
/bin/mkdir -p Include
python3.3 ./Parser/asdl_c.py -h Include ./Parser/Python.asdl
$ make Python/Python-ast.c
/bin/mkdir -p Python
python3.3 ./Parser/asdl_c.py -c Python ./Parser/Python.asdl


At least please fix the script used to generate tarballs, to ensure that this bug will not occur with future tarballs.
