Fixes in several README.md files

There are many more fixes to be made but I wanted these in. Even the
files I have checked will have to be checked again in more detail but I
needed these committed so I could fix something in another file that
will need a new branch. More updates to README.md files will then be put
into yet another branch if the pull requests have not yet been merged
before I get to these updates (which really ought to be a lot of
fun!  :-) )

 This program is a unique variation on the age old "Hello, world"
 program.  What reads like a read may be written like a write!
 
+NOTE: this entry will probably not work under macOS with the Apple chips (Intel
+should be fine though we have no way to test this). Although it will compile
+cleanly it will not print anything out. More specifically, on modern systems one
+might need to specify `-m32` but the Apple chips which are arm64 based will not
+compile this entry:

+We were able to get it to work under linux on a 64-bit machine without
+specifying `-m32`. However this will fail under the Apple chips because it is
+arm64. If we specify `-arch i386` it will not compile:
