Author: jilles Date: Fri Aug 30 10:45:02 2013 New Revision: 255068 URL: http://svnweb.freebsd.org/changeset/base/255068 Log: sh: Cast -1 to pointer rather than pointer to variable of wrong type. NEOF needs to be a non-null pointer distinct from valid union node pointers. It is not dereferenced. The new NEOF is much like SIG_ERR except that it is an object pointer instead of a function pointer. The variable tokpushback can now be static.
