Profiling features of libstdc++. It won't be pulled in unless anyone requests it: $ eg++ -D_GLIBCXX_PROFILE foo.cc (and running the program collects advice in a file called libstdcxx-profile.txt) Though it's not a big deal, since you can also define _GLIBCXX_HAVE_EXECINFO_H on the command line (see libstdc++-v3/doc/html/manual/profile_mode.html).
