That would be appreciated. I don't know if Steven agree with the
patches in current form, and he certainly suggested adjustments to fix
regression testing in the status folder here:

which JÅ©rgen tested without complete success. I basically get the same
result as JÅ©rgen with Jamroot
"alias headers" like this:

alias headers : : <dependency>$(all-headers)-headers
<dependency>numeric-$(numeric-headers)-headers : : <include>. ;

I am not sure that is what Steven suggested. However with this the
regression tests int the status directory are running successfully for
the vast majority of libraries.

The patches has a number of tests commented out in status/Jamfile.v2
which probably is not intended to be applied. I did not try to
uncomment them when I tested, I assume there was or are failures there.

fixed by Dave here

Ok, it seems to me that lacking b2 support for generating header
symlinks is the primary blocker for progress with git conversion now.
Someone with with better knowledge of b2 than me need to step up. At
least I need some directions as to what I may try.
