This is just notes that will be reordered and elaborated on later.

What to look out for…

• dos.m4 - Add && !defined __OS2__ to the long #if statement. See [3345] for an example.
• po.m4 - Fix the root slash detections. See [3344] for an example.

The .m4 files to are usually located in a m4 or config subdirectory.
