Whereas I thought about mentioning these things in the advice for porters file,
namely unix/PLATFORMS...

Yes, "auto" is the root cause. But root cause analysis and other technical
explanations belong in comments. A log message should indicate what has changed
(from the point of view of the user). In this case: intparam.c did not compile
and now it compiles again.

Thanks for explaining. They have reused a keyword to mean a completely different
thing. As usual in C++... Whereas in C# and Java it's called 'var'.
