Say, you have one file, a.cpp. You build the static library. Then, you change 
your mind and rename a.cpp to b.cpp. You build the static library. Now, the 
static library has two files with indentical comments, and if you use a 
function defined in both, you might pick up the old one. 

So, archive is removed and recreated. A bug in hpp_cxx.jam omitted some files 
from the 'archive' action. I've just fixed that bug, so all files should be 
passed to 'archive'.

Thanks for reporting!
