two comments: 

Hmm.  One generic comment for the entirety of the numerical changes (such as +6 becomes +7).  I would really like this to be more informative.  It wasn't much so before with +6 but as long as the numbers need to change, it would be nice to have a global value to use for such things.  I know this would be more work, but also more debuggable and maintainable going forward with open source.

Another generic comment: it appears that 32 and 64 bit are getting the extended stack size in your update?  It would be nice if this was saved for 64-bit only.  Mobile devices are (I'm pretty sure) 32 bit and need to save space.  What do you think?
