I can't speak to the Alsys binding, but the Apex binding
(with which I have considerable experience) is conformant
to IEEE Std 1003.5-1992, right down to the package names.

Just like Ada compilers have some implementation details,
the POSIX Ada binding also has some implementation lattitute.

Haven't done much with Florist. The anxiety I have is that
it a POSIX binding doesn't come from the compiler vendor,
then how is one to have confidence that the multi-tasking
aspects of POSIX threads are compatible with Ada tasks
and how are Text_IO Form parameters going to access POSIX
access and file control fields (just to name two issues).
