While we're on the subject, does anyone have experience with the following
assertions?
1. "cp -R" is not portable. Use "install -c" instead.
2. "-a" and "-o" are portable, insofar as automake relies on them.
3. "-e" is not portable to test for a file's existence. Use -r instead.
These are in the context of shell scriptlets in a Makefile.
I can't find any specific admonition not to use "cp -R" except that it's a
fairly recent innovation, and it's not a shell built-in, making it that
much more variable.
