Obviously neither of these affect builds on Red Hat Linux, but it would be
nice to have them fixed.

Problem 1:
- none of the C files include config.h. This specifically rpmmodule.c.

Solution 1:
- add a #include "system.h" to the top of each C file.
- remove #include <alloca.h> from the top of rpmmodule.c


Problem 2:
- PyObject_HEAD should not be followed by a semicolon.

Solution 2:
- for i in *module.c; do
      mv $i $i.bak
      sed "s/PyObject_HEAD;/PyObject_HEAD/g" < $i.bak > $i
  done
