Turns out first code worked as well --- branch just wasn't being 
entered. ECHO seems a pretty good way to debug jamfiles.

Using ECHO I discovered that -NO_COMPRESSION=0 actually turns 
NO_COMPRESSION *on*. So just leaving out all NO_* defines from command 
line improves things.

I did discover that bjam iostreams ... doesn't seem to create the 
libboost*.lib files... if I tack "stage" onto the end of the command 
line they *are* created... but everything is built, not just 
iostreams.... I must admit I find bjam fairly confusing.

So adding "stage" caused libboost* files to be created for zlib and 
bzip2... but now I get linking errors with bzip2. It complains that 
__thiscall boost::iostreams::detail::bzip2_base::~bzip2_base and several 
other functions in bzip2_base are not implemented...

hm...
