[Pyrex] Pyrex parser bug

[John J Lee]

The following file causes a traceback instead of a Pyrex syntax error
with Pyrex 0.8.2, Python 2.3b2 (0.7.2 / Python 2.2.1 also gives a
traceback).

Note the syntax error (using C-style () cast syntax instead of <>), and
that BLAH is a macro which is (unintentionally) not declared in the Pyrex
file.

------CUT HERE------
ctypedef int foo

cdef foo bar():
    cdef int i

    return (((foo)(i) << 1) | BLAH)
------CUT HERE------


Here's the tail of the traceback:
