7# The resulting diff is suspiciously large.

26# Check which exported symbols from libpthread are never referenced
27# from other libraries. Generally, I'd expect a very few __functions
28# with two underscores to be exported and not used by e.g. libc-X.X.X.so,
29# as these names are supposed to be internal, i.e. external programs
30# usually don't call them. On my system, I got 141 such __functions.
31# Examples:
32# __flockfilelist - NOP function (why do we need it at all?)
33# __pthread_perform_cleanup - called only from within libpthread
