I would presume it is in the GNAT documentation.

I would think the fact that GNAT also implements it would be a good
reason.  DEC Ada is still used on VAX and Alpha, but is not being
ported to the Itanium implementation of VMS.  No new features are
being added, but support is available from HP.  The current name
is either Compaq Ada or HP Ada, depending on how far the renaming
police have gotten.

I was referring to calling other languages, not inlining.
