use the new names exclusively, and the linker will see the new names. Files that import "Python.h" also only see the new names. Files that import "allobjects.h" will continue to be able to use the old names, due to the inclusion (in allobjects.h) of "rename2.h".

Note: 'digit' should be able to hold 2*MASK+1, and 'twodigits'
|
|
should be able to hold the intermediate results in 'mul'
|
|
(at most MASK << SHIFT).
|
|
Also, x_sub assumes that 'digit' is an unsigned type, and overflow
|
|
is handled by taking the result mod 2**N for some N > SHIFT.

And, at some places it is assumed that MASK fits in an int, as well. */
