* mach/Versions (libc: GLIBC_2.0) [SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_1)]: Conditionalize __vm_allocate on this. [SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_2)]: Conditionalize mutex- and spinlock-related symbols on this. [!SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_2)] (libc: HURD_CTHREADS_0.3): New version set. Lock-related symbols go here instead in this case. * sysdeps/mach/hurd/Versions (libc: GLIBC_2.0): Remove _cthread_exit_routine, _cthread_init_routine, cthread_keycreate, cthread_getspecific, cthread_setspecific, __libc_getspecific. * hurd/Versions [SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_2)] (libc: GLIBC_2.0): Put them here instead. [!SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_2)] (libc: HURD_CTHREADS_0.3): New version set. Those cthreads symbols go here instead in this case. * Versions.def (libc) [USE_IN_LIBIO]: Add HURD_CTHREADS_0.3 version.
