Bug in error reporting when type does not exist

[robertwb]

Entire test case is embedded in error message:

Error converting Pyrex file to C:
------------------------------------------------------------
...

cdef NonExisting* ptr
cdef object o
ptr = o
      ^
------------------------------------------------------------

/home/dagss/cython/structbuffer/test.pyx:4:7: Cannot convert Python object to '<error>'

There should be a more friendly error message here.

Migrated from http://trac.cython.org/ticket/98

Ideally, the non-existance of NonExisting should be the line to raise any error, and that should invalidate the declaration of ptr and the assignment so that they don't raise further errors.
