Hi,
I updated the visual C++ compiler from 17.0.6 to 17.4.6 and I'm getting a compilation error by including <boost/range/mfc.hpp>:
1>\boost\range\detail\microsoft.hpp(626,33): error C2440: 'return': cannot convert from 'const void *' to 'const void *&'
1>\boost\range\detail\microsoft.hpp(624,1): message : while compiling class template member function 'const void *&boost::range_detail_microsoft::list_iterator<const X,const void *,boost::use_default,boost::use_default>::dereference(void) const'

The project is compiled with /std:c++20 switch.
This is easily reproducible - it is just needed to create a C++ console application, add the include to <boost/range/mfc.hpp> to one cpp file, add boost directory to include directories and set the compiler flag /std:c++20.
I'm using boost 1.81.
Best regards,
Gabriel
