Can you describe what you mean by "the appropriate glibc"? There's no direct relationship between the versions of glibc and GCC, for the most part. It's not clear to me why a suite of lock-free data structures would care about which version of glibc was being used for test; do these implementations depend on glibc functions in some way?
