[New-bugs-announce] [issue42304] [easy C] long type performance waste in 64-bit Windows build

[Ma Lin]

New submission from Ma Lin <malincns at 163.com>:

C type `long` is 4-byte integer in 64-bit Windows build (MSVC behavior). [1]
In other compilers, `long` is 8-byte integer in 64-bit build.

This leads to a bit unnecessary performance waste, issue38252 fixed this problem in a situation.

Search `SIZEOF_LONG` in CPython code, there's still a few long type waste.

Novices are welcome to try contribution.
