What do you mean by a "raw string?" The list of
properties should contain <embed-manifest-file>object(file-target)@NNNNN
which you can extract with
[ feature.get-values <embed-manifest-file> : $(properties) ]

Yes. b2 creates a temporary batch file and
executes it with cmd.exe. If I need to access
a variable like this in the rule, I usually use
flags msvc.manifest MANIFEST_FILE <embed-manifest-file> ;
rule manifest ( targets * : sources * : properties * )
local file = [ on $(targets) return $(MANIFEST_FILE) ] ;

Are you sure about that? b2 is supposed delete targets
that failed to update. It does relink when the existing
embed-manifest handling fails (which happens on a regular
basis "mt.exe : general error c101008d: Failed to write
the updated manifest to the resource of file "xxx.exe".
The process cannot access the file because it is being
used by another process.").
