Hello Pascal,
I think I will follow your advice and will use the annotated
libraries. I understand that whenever I am going to use standard
libraries I should replace these with the annotated ones.

In my example, I will probably not use standard libraries because my
example is from a safety domain and standard libraries are considered
with concern.

In the embedded domain, we are using sometimes specific compilers that
come with specific libraries. In that case, do I have to annotate them
myself in order to make analysis work?
