OK, if you think user-config.jam is the way to go then we do it this
way. Of course, I'll reflect the necessary changes in gil::io

Can we just define the source code path like this, inside user-config.jam:

using zlib : 1.2.5 : c:/chhenning/zlib/zlib-1.2.5

If so, how would the gil::io jam file pick up the path?

As you probably can guess I'm not very familiar with configuring jam
files. Any help from your side would be very appreciated.

Please let me know what I have to do make it to work.
