I have done some investigating on this. The problem appears to be in
common.jam(536): rule response-file

Chaning line 583: "print.output $(rsp)" to

echo response file $(rsp) ;
print.output "console" ; # $(rsp) ;

gives:

response file 
<p..\..\..\build\tools\music\msvc-7.1\release\user-interface-gui\w
in32-charset-unicode>main.obj.rsp

-DFOO
-DNDEBUG
...

so it *is* picking up the changes (-DFOO), but these aren't being passed 
on to the file. Therefore, the problem is in the util/print.jam logic. 
(Should the response file set output to overwrite the contents?)

NOTE: I have tested this from both NT/cmd and cygwin/bash with the same 
effect.
