PR to apply this fix to boost: boostorg/graph#269 .

I do not seem to have permission to view the logs for the CI failure, so I don't know what the "unexpected error" is -- in any case it is for a configuration that should not be affected by this patch at all.

For the record, this patch has been accepted into boost::graph on develop:
boostorg/graph@fa3bd05

https://github.com/boostorg/graph/pull/269/files

Thanks for taking the time to see that through

Failure in build 2 (c268543a4f94a2317517924166f6c6803b6f0195):

An unexpected error happened and has been reported. Help is on its way! 🏇

I am going to close this, since the consensus is that we shouldn't apply code patches to libraries, and I can keep using my workaround until the next version of boost graph is released.
