-KNOWN ABI BUGS
---------------
-
-  time_t is 32-bit. http://b/5819737
-
-  off_t is 32-bit. There is off64_t, but no _FILE_OFFSET_BITS support.
-
-  sigset_t is too small on ARM and x86 (but correct on MIPS), so support
-  for real-time signals is broken. http://b/5828899
-
-  atexit(3) handlers registered by a shared library aren't called on
-  dlclose(3); this only affects ARM. http://b/4998315
