AmberTools Bug Fixes and Updates

Note: The individual bug fixes for AmberTools are described below in case you want to see what they do, or apply patches by hand. Most users are encouraged to use the update_amber script (which is automatically run during the cmake step) to handle patching tasks. This script automatically downloads and applies patches on this site individually and keeps track of every patch that has been applied, making patching and trouble-shooting easier.

Instructions for using update_amber can be found in the Amber 2023 Reference Manual in Chapter 2, Section 4, or just go to your amber22_src directory and type

./update_amber --help

If you wish to apply the listed AmberTools updates, run cmake again.
