Linux is still not quite as easy to use as Mac :-(. Multiple gcc are not
usually available on Linux.

Yes there is. The problem is the search path for DLLs. The path of an DLL is
hard-coded into the executable. There is also an additional search which
can be set in /etc/ld.so.conf.d when the DLL is not found at the "usual"
place.

But that is all manual extra installation and can be quite tricky - nothing
I would want dump on an unwary beginner of Ada.
