Inspect include/boost/test/impl/progress_monitor.ipp around line 61, then reproduce the warning with MSVC 143 in Boost.Test header-only mode using "included". Check whether the variable modification in the condition is related to C5045; done means the warning's cause and an appropriate correction or confirmation are established.

https://github.com/correaa/boost-multi/actions/runs/10066511703/job/27828050365#step:9:62
