[build] b2 headers broken?

Currently all CI seems to be failing during b2 headers, but with no 
obvious error message, see for example: 
https://drone.cpp.al/boostorg/multiprecision/23/1/2

Only possible thing I can see is:

project-config.jam:10: syntax error at keyword in

Anyone any ideas?

Many thanks, John.
