Florist is an implementation of a standard for Ada-POSIX bindings, 
https://www.iso.org/standard/34354.html, so the Florist API should not 
be GNAT-specific.

However, the implementation of Florist may depend on the underlying 
system, including the Ada compiler and the OS.

Using the Florist API, rather than using GNAT libraries or OS functions 
directly, should increase the potential portability. Actual portability 
will depend on the existence of implementations, for the target system, 
  of Florist or other realizations of the standard Ada-POSIX binding.
