Unfortunately, the patch doesn't work for me.

I'm still having to use my hack-o-matic script (attached here), which:
  * does a test compile of a pyrex-generated .c file
  * parses the errors
  * automatically adds the missing '__pyx_knnnp' decs to the c file

If you're using a Makefile-based build, you can change this or similar 
rule in your Makefile:

    myfile.o: myfile.pyx
            pyrexc myfile.pyx
            gcc -c $(MY_FAVOURITE_C_FLAGS) myfile.c

to:

    myfile.o: myfile.pyx
            pyrexc myfile.pyx
            python hackpyrexc.py myfile.c
            gcc -c $(MY_FAVOURITE_C_FLAGS) myfile.c

This has been working out well for me.
