Regression: Possible precedence problem between ! and numeric eq (==)

[IgorTodorovskiIBM]

We're seeing this in a couple of perl scripts now:

Possible precedence problem between ! and numeric eq (==) at /data/zopen/usr/local/zopen/automake/automake-1.17.20241029_040611.zos/bin/automake line 6875.

This warning was added to perl because code was not doing what was intended due to confusion over precedence. It found real bugs, but also has false positives. The solution to getting this error is to examine the code and add parentheses to get the intended meaning or silence the warning.
