New + applications do not link with -lpthread, -ldl, -lutil, -lanl anymore. + For backwards compatibility, empty static archives libpthread.a, + libdl.a, libutil.a, libanl.a are provided, so that the linker options + keep working. Applications which have been linked against glibc 2.33 + or earlier continue to load the corresponding shared objects (which + are now empty). The integration of those libraries into libc means + that additional symbols become available by default. This can cause + applications that contain weak references to take unexpected code + paths that would only have been used in previous glibc versions when + e.g. preloading libpthread.so.0, potentially exposing application + bugs. + * When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, PTHREAD_STACK_MIN is no longer constant and is redefined to sysconf(_SC_THREAD_STACK_MIN).
