This cleans up the "easy" warning fixes which can be made using my

Regress script, comparing object-files before/after the edits:

https://invisible-island.net/scripts/readme.html

The changes are casts, which quiet the gcc warnings about implicit conversion that my "gcc-normal" script would show. I avoided reformatting the code.

The change reduces the number of gcc warnings from 769 to 163.
