Some additional googling pointed to bug in SDL-1.2.14. I was using that version. See http://bugzilla.libsdl.org/show_bug.cgi?id=849. Unfortunately SDL-1.2.15 is not released and they changed from svn to hg, so it's harder get the patch that went in. But there's a contributed patch in the comments, so I'll test it quickly.
