Fix a bug in my last commit, symbol macros that expand to themselves hang. 2011-06-19 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el (cl-defsubst-expand): It is occasionally the case that the symbol naming the argument co-incides with the value that it is replacing; in that case, using the symbol macro is counterproductive and hangs XEmacs (as does analogous code in SBCL), so don't.
