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!
