OK I got the Jamfile building OK, but now I see an error in the postprocess 
step:

profile_templates.process_raw_profile 
..\..\..\bin.v2\libs\profile_templates\test\msvc-8.0\debug\threading-multi\test.tp

    "..\..\..\bin.v2\libs\profile_templates\src\msvc-8.0\debug\threading-multi\postprocess.exe" 
<"..\..\..\bin.v2\libs\profile_templates\test\msvc-8.0\debug\threading-multi\test.rtp" 
 >"..\..\..\bin.v2\libs\profile_templates\test\msvc-8.0\debug\threading-multi\test.tp"

...failed profile_templates.process_raw_profile 
..\..\..\bin.v2\libs\profile_templates\test\msvc-8.0\debug\threading-multi\test.tp...
...removing 
..\..\..\bin.v2\libs\profile_templates\test\msvc-8.0\debug\threading-multi\test.tp

A couple of other observations:

* This takes an absolute age to run... isn't there a better way than 
processing all the Boost headers separately?  Maybe pre-process the source, 
then insert the special markup and compile?
* If a failure occurs and I re-run the Jamfile, then it just goes off 
processing all the Boost headers all over again, so there's some dependency 
analysis missing somewhere :-(

Cheers, John.
