Reported by Akim Demaille at <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html> and discussed again starting at <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>. * data/bison.m4 (b4_percent_define_default): Leave syncline blank because location information is bogus. Use angle brackets to delimit fake file name because square brackets look like over-quoted m4. Choose a better fake file name. Use negative line numbers. * src/muscle_tab.c (muscle_percent_define_default): Likewise. * src/location.c (location_print): If line for a boundary is negative, only print that boundary's file name. * src/location.h: Document that. * tests/skeletons.at (%define Boolean variables: invalid skeleton defaults): Update output.
