Subject: For PE files, copy dos_message contents from source binary
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="------------2.23.0"
This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=fixed
Content-Transfer-Encoding: 8bit
Wine uses a special message in this area to mark its own binaries.
strip(1) would discard the message from the original binary and replace
it with a hard-coded string. This would break Wine when its libraries
are built as PE files and installed with strip(1).
For example, see the special message in the original DLL from a Wine
build tree, starting at offset 0x40:
$ xxd ~/src/wine.win64/dlls/ieframe/ieframe.dll | head

This patch copies the message from the original binary into the new
binary.
