I use CVS and I updated a couple days ago.

Yes, that's it.  I should probably disable optimized builds for now
anyway.

Not that I saw.  'libhello.so' does exist though.  It's a link to
'libhello.so.0.0.0' in the same directory.  Also, 'libhello.so.0' in the
same directory is a link to 'libhello.so.0.0.0'.  There is also
'libhello.a', 'libhello.la', and 'hello.o'.

I used lib/Transforms/Hello/Hello.cpp provided in the CVS tree.  It has
exactly the line of code you require.  I also used the Makefile there.

If you think of anything else, please let me know...
