No, you misunderstand. The package may or may not be available in 3.15, but=
 if=20
it is, it will be equally non-portable.

It is a 'conveniance' package provide by the compiler-vendor, not a package=
=20
required to be distributed with all Ada compilers.=20

It's nothing wrong with it, just that it _might_ not be present when you us=
e=20
another compiler, like Object Ada..

You can use it, or not. (If not do a 'pragma Import' on getenv, if your=20
targets are all unix)
