1 comment and 1 question about 30bit_longdigit20.patch:
 - I love fixed size type: you use them when PYLONG_BITS_IN_DIGIT == 
30 (eg. digit=PY_UINT32_T) but not when PYLONG_BITS_IN_DIGIT == 15 
(eg. digit=unsigned short). Even if short is always 16 bits, I would 
prefer fixed size types in any case.
 - In pyport.h, you redefine PYLONG_BITS_IN_DIGIT if it's not set. Is 
it for the Windows world (which doesn't use configure script)?

I prefer the patch version 20 because it's much simplier than the 
other with the algorithm optimisations. The patch is already huge, so 
it's better to split it into smaller parts ;-)
