So far, nothing in this thread is specific to building Boost,
as opposed to some other C++ library ;-) However, this time
we can continue it here.

Did you run configure? I think that's the only way a user-config.jam
can be generated in the root folder. I'm meaning to raise the
issue of 'configure' doing slightly confusing things on the devel list.

I'm afraid this will require some manual work -- as presently, 
when running on windows, boost.build assumes you're targeting windows.
For quick result, go to

        tools/build/v2/tools/gcc.jam

and locate code fragment that goes like:

if [ os.on-windows ]
{
    .IMPLIB-COMMAND = "-Wl,--out-implib," ;
    ...
}
else
{
}

Remove everything starting from "if" up until, and including, the "else".
Let me know what errors, if any, remain after that.
