Thanks for your quick reply. Filesystem also did not change between the
two versions.
I tried to use the Jamfiles from 1.57 to build 1.58, but that did not
work. Even when copying the old context/config from 1.57 there were
errors because the same config target had been built twice (error:
unknown feature "<abi>"). I have not had time to look for differences
between context/config config/checks/architecture but since these were
recognized as the same project by bjam is it safe to assume they are
very much the same?

That does not work, since I can not set <abi> in my local Jamfile,
because it is reported as an unknown feature. Is it possible to declare
properties like <abi> inside Jamfiles which should be referenced in my
local Jamfile explicitely?

thanks,
Norbert
