Make the code compiles on Windows

[rgiot]

I have no issues a all to compile these crates under Linux and to use them as dependencies of other projects.

However, I know nothing to windows compilation world and I hit an issue I am unable to solve myself. Some guidance is expected. The cradte does not compile on windows. Neither on my machine or the github pipeline.

I am pretty sure at the early stages of development of these crates, I have been able to build them at least with one of these versions of rustc.
I do not expect anyone to solve the issue at my place, but I will be very greatful to have some guidance to know where to look at.
