When using the -s flag of gnat make, the flag -gnatW8 is stripped during
switches comparison (and therefore forces unnecessary compilation).
Example:
> cat dummy.adb
procedure Dummy is
begin
null;
end;
> gnat make -v -s -gnat05 -gnatW8 dummy

"dummy.ali" being checked ...
-> "dummy.adb" different number of switches
-gnat05 -gnatW8
-gnat05
gcc-4.4 -c -gnat05 -gnatW8 dummy.adb
End of compilation
gnatbind -x dummy.ali
gnatlink dummy.ali
The line "-gnat05 -gnatW8" has the flags used at the previous compilation (they
are correct). The line "-gnat05" has the flags used for the current compilation
(they are incorrect: -gnatW8 given on the command line was stripped here).
The unit is recompiled also the expected behavior was not to do it.
