If by "libraries" you mean run-time (target) libraries, feel free to use
non-standard features, since that is not a boot-strapping problem.  The
issue is the compile-time (host) code that is written in Ada.  That code
really should be written to minimize dependencies on a specific compiler
version, whether it is written in C, C++, Java, or Ada.
