# The Android linker has some unusual behavior: No matter what
# path is passed in to dlopen(), it'll only use the path's
# basename when trying to find a cached library.
# Unfortunately, this is quite problematic for us, since for example,
# Hash::Util and List::Util both end up creating a Util.so --
# So if you load List::Util and then Hash::Util, the dlopen() for
# the latter will return the handle for the former.
# See the implementation for details:

# These tests originally looked for 'FIX' or 'Android' warnings, as they
# indicated stubs to avoid. At some point, Android stopped emitting
# those warnings; the tests were adapted to check function return values
# and hopefully now detect stubs on both older and newer Androids.

# These are all stubs as well, but the core doesn't use them:
# getusershell setusershell endusershell

# This script UU/archname.cbu will get 'called-back' by Configure.

# Android 8.x: <no warnings; tests now printf a compatible warning>
