To me this reads: do not call this from a shared library; however your
main program can call this even if it is in a shared libgnat. There is
no technical reason why g-trasym.adb cannot be compiled with -fPIC and
included in a shared library. For that matter, if we followed your
interpretation, g-trasym.adb should not be in a static library either.
