`ar.exe` tries to load libdep.a (from lib\bfd-plugins) as a DLL and fails

[reznikmm]

If I build

gprbuild -P langkit_support.gpr -p

on running ar.exe a error dialog appears with a message like

C:\alire\gnat_native_11.2.2_b741ebbc\lib\bfd-plugins\libdep.a is not a windows program and can't be run

When I press Ok button it works after all.

Files are:

• langkit_support.ads

  package Langkit_Support with Pure is
  end Langkit_Support;

• langkit_support.gpr

  
  library project Langkit_Support is
  
  for Source_Dirs use (".");
  for Object_Dir use "obj/";
  
  for Library_Name use "langkit_support";
  for Library_Kind use "static";
  for Library_Interface use
   ("Langkit_Support");
  
  for Library_Dir use "lib/";

end Langkit_Support;

Perhaps this is related.

I also found this: https://github.com/msys2/MINGW-packages/blob/68b22c4a024bf434635441c6ce5ffc3e7cf8a220/mingw-w64-binutils/PKGBUILD#L134

Fixed in #26

This problem is still present in gnat-11.2.0-4. I get the same error message dialog as described in the description, and I can see that libdep.a is still present in the installation at gnat_native_11.2.4_2f9c5d6d\lib\bfd-plugins\libdep.a. As a workaround I manually deleted this file and the error dialog goes away and my library is still built successfully.
