First, thanks much for your response. I'm running testing, so I apt-get'd g++-3.2 just now with no problem and tested out boolalpha, and presto, it worked! Thanks. Second, question about how to best set up the dual compilers: Like you, I'll use 2.95 to compile downloaded software, and 3.2 for stuff I write. Do you change the symlink in /usr/bin depending upon what you are doing? Is there a better way such that you won't forget to change that symlink cause I know sooner or later I'll forget. When I compile my own stuff, I use qmake. So it's easy enough for me to have qmake.conf point to 3.2. Is there debian package software that uses qmake? If not, then I can leave my symlink in /usr/bin pointing towards 2.95 and just change the pointer in my qmake.conf.
