[Boost-build] Compiling dozens of files called main.cpp

I'm trying to compile dozens of files in countless subdirectories. I came  
up with this simple Jamroot file as all files are called main.cpp:

import testing ;
compile [ glob-tree main.cpp ] ;

Bjam doesn't like this though and shows the error "Duplicate name of  
actual target". There is an entry in the FAQ at  
http://www.boost.org/doc/libs/1_41_0/doc/html/bbv2/faq.html#id2181242 but  
as far as I can tell the problem is different here: I'm not trying to  
compile the same file twice but many different files in different  
subdirectories - but all files happen to be called main.cpp (as they are  
stand-alone programs). As Bjam wants to compile all files in bin/main.test  
though the error pops up. I wonder if there is a work-around to trick Bjam  
(as the above Jamroot file would be really simple; ideally I don't want to  
drop the glob-tree rule and don't want to put a Jamfile into each and  
every subdirectory)?
