NULL is "Invalid compile-time expression" with embedsignature=True

[robertwb]

With Cython 0.22, Cythonizing

#cython: embedsignature=True
def foo(char* v=NULL):
    pass

gives

Error compiling Cython file:
------------------------------------------------------------
...
#cython: embedsignature=True
def foo(char* v=NULL):
               ^
------------------------------------------------------------

example.pyx:2:16: Invalid compile-time expression

The compilations works fine with embedsignature=False.
