One such warning is

p.adb: Warning: line 10 col 10 LRM:2.8(11), Unrecognized pragma name =>
"unreferenced", Continuing

With programmable IDEs, warnings can be ignored inasmuch as the IDE
allows classifying and filtering messages. One easy way to achieve
this is to ignore messages that have uniquely identifying substrings.


  To_Be_Ignored.Append ("Unrecognized pragma name => ""unreferenced""");

  Pattern := +"";
  for Warning of To_Be_Ignored loop
     Pattern := Pattern or Warning;
  end loop;

Then, something like

$ gnatmake -Pfoo 2>&1 | grep -v "${Pattern}"
