Many thanks.
Everything is now fixed including the warnings.
Tested on Linux ARM/Aarch64 and Windows 32/64 using reproducible build.

Sure, I was only talking about the "library 'c' not found" problem. At
home I could now also test ARM: I was distracted while doing the last
patch so it wasn't complete. Now fixed as well, and ARM now works again.
(I've also fixed the aligned_function address test)
Ciao,
Michael.
