This is right. libultrasparc4.so is part of NSPR.
If you don't use it, your application still works
correctly.
It is tricky to use. Here is the recommended setup:
installdir/libnspr4.so
installdir/libplc4.so
installdir/libplds.so
installdir/libultrasparc4.so
installdir/sun4u/libatomic.so --> ../libultrasparc4.so (a symlink)
Your application should be invoked by a shell script
wrapper, which sets LD_LIBRARY_PATH to contain 'installdir'.
If 'uname -m' returns sun4u, add installdir/sun4u to
LD_LIBRARY_PATH.
If you don't do this, NSPR still functions correctly.
It just won't be able to use the UltraSPARC atomic
instructions when running on 'sun4u' systems.
