Move macros with shadows in bytecomp.el to the end of the files, cl-macs lisp/ChangeLog addition: 2011-10-08 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el: * cl-macs.el (load-time-value): * cl-macs.el (flet): * cl-macs.el (labels): * cl-macs.el (the): * cl-macs.el (declare): Move all these macros to the end of the file, since they're in byte-compile-initial-macro-environment, and we don't want their definitions to override that for the rest of the file during byte-compilation. Happens not to matter right now, but avoids surprises for anyone using the macros elsewhere in cl-macs down the line.
