>Description:
MIT krb5-1.4 uses pthread_equal(), so could you consider
adding pthread_equal() stub to libc (and pthread.h)?  I think that
unconditionally returning 1 is enough for non-threaded applications.

NetBSD's libc doesn't have a stub for pthread_equal(), but
MIT krb5 is weak-referencing pthread_equal().
Therefore the absense of pthread_equal() is not detected on the
link-time, and programs using krb5 mysteriously dies at run-time.
(unless the application is linked with libpthread)

>How-To-Repeat:
Install MIT krb5-1.4 (or pkgsrc/security/mit-krb5 1.4 or later) and
run kinit from it.
