Give the label name when warning or erroring, bytecomp.el 2011-11-02 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el (byte-compile-lambda): Accept a new NAME argument here, have byte-compile-current-form reflect that if it's specified. * bytecomp.el (byte-compile-initial-macro-environment): Specify the label name when byte-compiling it, so warning and errors are more helpful.
