I tried running the v2 tests with cygwin python and cygwin built bjam, but I
just got a long list of python error messages (none of the tests actually

No idea at all, I just did a web search for the errors I was seeing and
those were the options suggested, the most important thing though is to get
rid of the version suffix on the dll name: cygwin will not link to a dll
unless it ends in ".dll". Once that's sorted we can see what other options
may still be needed.

I tried building quickbook like that but got:

error: on gcc, DLL can't be build with <link-runtime>static
error: it's suggested to use <link-runtime>static together with the

Building with link=static seems to do what I really wanted though.

I can't remember exactly where I saw this, but
mentions <runtime-link>static.

BTW is there a list of feature variants somewhere? I was looking for the v2
equivalent of <sysinclude> the other day, but couldn't find it, likewise it
wasn't really obvious to me that <link>static was what I really wanted: if
there was a central list that explained the options and what the differences
between them were that would be a big help IMO (of course I may have just
missed it!).
