gcc warns of unused variables in module initialization

[robertwb]

I create foo.pyx containing either or both of the following statements:

  cdef double INFINITY = float('inf')
  assert True

I build it using Cython 0.9.6.13.1 and gcc 4.1.3. The build succeeds and the code works, but gcc issues the following warning:

  foo.c: In function ‘initfoo’:
  foo.c:130: warning: unused variable ‘__pyx_4’
  foo.c:129: warning: unused variable ‘__pyx_3’

I see no such warnings when building the same code under Cython 0.9.6.12.

this isn't broken, it's just that temps are allocated prematurely

this works for me now (see test case in run/specialfloat.pyx)
