This fixes a recent regression introduced in the machinery giving style
warnings: the -gnatyN switch no longer cancels an earlier -gnaty switch
for separate compilation units.
Running this command:
gcc -c slib.adb -gnatyaAbcefhiIklmM25OnprStux -gnatyN
On the following sources:
package Slib is
procedure I_Am_Short;
end Slib;
with Ada.Text_IO; use Ada.Text_IO;
package body Slib is
-- have a long line here as well.
procedure I_Am_Short is separate;
end Slib;
separate (Slib)
procedure I_Am_Short is
begin
Put_Line (".......................................................");
end I_Am_Short;
Should execute silently.
Tested on x86_64-pc-linux-gnu, committed on trunk
