--- Comment #13 from vsz.bugzilla at emailuser dot net ---
Repeating the minimal tests with MSYS2
`mingw-w64-{i686,x86_64}-binutils-2.27-4-any` (the build that includes the
proposed patch), it seems the problem is now fixed for both 32-bit and 64-bit
targets. UPX 3.91 is silent now and the previously visible default manifest
bits are no longer there inside the `.exe` files when a custom Windows resource
is linked.

Thanks to all for all the efforts and to Nick for the patch!
