Hi,

I have a problem I've tried to fix for hours, that is linking the
libraries fails
because the command-line input is too long for Windows to handle. I have
tried reading the boost documents, googling for the problem, and defining
my own variant rules to no awail.

I suspect this is a very simple problem in principle, but I just haven't been
able to find how to fix it. Basically, how can I reduce the command-line length?
It seems to me the build directory contains too many levels, I'd like
to just specify
a single level and maybe that would be enough. In the example I'm pasting,
each library seems to be built into a sub-directory of
"gcc-mingw-4.4.0\release\link-static\threading-multi". I suspect that if I can
in someway reduce that to "my-mingw" or something, I'd have a chance
to build the library.
Anyone know how to do that?

Here's one example of the error message:
