My Boost lib directory had .a files as well as .dll files. I discovered, 
using MinGW GCC 3.4.5, that the presence of the .a files is causing 
static linking (I should have realised that). So I delete the .a files 
and I get dynamic linking. Woops. I guess I should have these DLLs and 
static libraries in different directories, so that I can select which I 
want.
