This will become an urgent issue with glibc 2.34, which defines pthread_mutexattr_gettype unconditionally. Certain gnulib modules will stop working until the binaries are relinked.
Thanks for mentioning this. But in what sense will the modules stop working? I'm a little lost.
glibc 2.34 also defines pthread_once unconditionally, right? So why doesn't code like this:
if (pthread_mutexattr_gettype != NULL) pthread_once (control, callback); continue to work in 2.34?
