Thanks for your response. I agree with that, but it was just a simple
case to demonstrate the behavior. Originally, the problem is with
"resource-only" dll on Windows with MSVC toolset. Is there any reason
for a target to be rebuild if none of its sources/dependencies were changed?

Is it possible to prevent unnecessary rebuilds of resource only dlls?
Here is an example:
### jamfile.jam ###
lib aaa : a.rc : <link>shared <linkflags>/NOENTRY : <toolset>msvc ;
---
### a.rc ###
STRINGTABLE
BEGIN
123 "some text"
END
---
Thanks,
