In zsh's eyes, it's a feature, no doubt. If zsh pretends to be Bourne
shell compatible, it's a bug.
During the installation, I'm trying to determine if the shell that's being
used is at least basically Bourne shell compatible. The zsh doesn't qualify,
at least not when it exhibits this behaviour by default.

I have no problems with that, but if that is the case, the make utility
should *not* be allowed to pass on SHELL=/bin/zsh, because it's not Bourne

That's exactly the point. I can't go in and change *every* shell script
to use "setopt shwordsplit" at the start just to make sure that it
works with a zsh (and generates an error with every other shell).
I intend to check if the default behaviour of the shell is Bourne
shell compatible. And if the test fails, it isn't.
