It can result in a number of deprecation warnings, though, and if you 
have -Werror enabled that could be problematic for you. Our project 
includes a bunch of headers from a large third-party library that 
trigger these warnings, but telling g++ that they are 'system headers' 
makes it stop converting them to errors when -Werror is in use, so we've 
been able to work around it.
