Despite my attempts [1] & [2] to figure out what is going wrong
that prevents GIL docs from being generated.

The local `cd libs/gil && b2 doc` workflow is fine
- first doxygen generates files in doc/html
- then, sphinx-build generates files in doc/html
for both, master and develop.

Is it possible that this GIL top-level Jamfile in master
https://github.com/boostorg/gil/blob/master/Jamfile
with C++11 checks is the troublemaker here?
i.e. the checks fail on the machine where the Boost docs aregenerated

In GIL develop, after an advisory round from Peter and Rene,
I have removed moved the big-fat content from the top-level
Jamfile to test/Jamfile, here is the change
https://github.com/boostorg/gil/commit/4ed7701b47764edf327e7c82f65cf9815026bdc2

How do I know if that is the issue?
If it is, then shall I cherry-picl this restructuring commit into master?
