I've already been bitten by that kind of issue.
Now when I want to be "extra-sure" of my source/build tree state I:
- remove the build tree completely
- use the VCS at hand to clean the source tree, e.g. with git
git -fdx being in the root source dir should remove all non versioned
files (or directories) including ignore ones.
(there are more interesting feature to git-clean:
https://git-scm.com/docs/git-clean)
Then you can be sure to have a "clean" starting point.
Alternatively checking out the project in a separate place works as well.

So this was not the problem. The problem was that on the Mac I had build<br>
the system before using the autoconf/make suite, which had created<br>
`swipl.prc` in the source tree. Now, this is the second time I've been<br>
