[Boost-build] BB-on-Windows woes

To give my new code some cross-platform testing, I started up a Windows
10 VM and tried executing `b2` there. Doing this in the Boost.Python's
'doc/' directory (i.e., with this Jamfile:
https://github.com/boostorg/python/blob/develop/doc/Jamfile), I get this
output:

Z:\projects\modular-boost\libs\python\doc>..\..\..\b2
Z:/projects/modular-boost/tools/build/src/build\feature.jam:326: in
validate-feature from module feature
error: unknown feature "<format>"

Z:\projects\modular-boost\tools\build\src/kernel/bootstrap.jam:139: in

Z:\projects\modular-boost\boost-build.jam:17: in module scope from module

Can anyone help me understand why I'm seeing an error (" unknown feature
"<format>" "), and how to resolve this ? As no-one has complained about
that Jamfile, I'd expect this to be a setup issue on my (virtual)
machine. Any ideas ?

Thanks,

        Stefan
