[pypy-dev] Using PyPy as a compiler

[Hart's Antler]

Hi Holger,

I tried pyrexc in pypy/tool but i get the same error as with the normal pyrexc:
bash-2.05b# dist-pypy/pypy/tool/pyrexc test.pyx 
/root/imp/test.pyx:5:17: Declarator should be empty
/root/imp/test.pyx:5:17: Expected '>'

The pyrex generated code looks like this:
def hi():
  return hi__2ad67a3c()
cdef object hi__2ad67a3c():
  # untyped variables: v0 v13 v21 v3 v7
  v3 = <Function sys_stdout>()
  v7 = <Function print_item_to>('hello world', v3)
  v13 = <Function sys_stdout>()
  v21 = <Function print_newline_to>(v13)
  v0 = None
  return v0


which was generated from a function that looks like this:
def hi(): return 'hello world'

Cheers,
-brett
