 Thanks Michel for looking into it.  I was able to reproduce the warning
 message with this code in main.cpp:

 {{{
 #include <boost/algorithm/string.hpp>

 int main()
 {
   return 0;
 }
 }}}



 Although not too exciting but perhaps helpful, the build log
 (CPPRocksProject.log) capturing the compile switches and warning message
 looks like:
