If you go through the hoops of modifying these headers to fulfill R’s requirements, I’m sure it would be of interest to others if you contribute these back to BH. 

The danger obviously is that this gets out of sync with boost, which would create work for merging your changes to new boost files from the future. 

Some parts of boost (e.g. uBlas) have macros to control whether or not std::cerr is used at all. https://github.com/eddelbuettel/bh/blob/cb1427c27dc068c8328fd1d2f4b1b8a8da1957c2/inst/include/boost/numeric/ublas/exception.hpp#L215 <https://github.com/eddelbuettel/bh/blob/cb1427c27dc068c8328fd1d2f4b1b8a8da1957c2/inst/include/boost/numeric/ublas/exception.hpp#L215>

But I don’t think this is of any relevance to the files you want to use.
