interfaces. * data/bison.m4 (b4_percent_define_get_loc): New. (b4_percent_define_get_syncline): New. (b4_percent_define_flag_if): Use b4_percent_define_get_loc. (b4_percent_define_default): Record defining location as line 1 rather than 0 for the sake of synchronizing #line's, and define b4_percent_define_syncline(VARIABLE). (b4_percent_define_check_values): Use b4_percent_define_get_loc. * src/muscle_tab.c (muscle_syncline_grow): New. (muscle_code_grow): Use muscle_syncline_grow. (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and define b4_percent_define_syncline(VARIABLE). (muscle_percent_define_get_loc): New. (muscle_percent_define_get_syncline): New. (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and remove some unused variables. (muscle_percent_define_default): Record defining location as line 1 rather than 0 for the sake of synchronizing #line's, and define b4_percent_define_syncline(VARIABLE). (muscle_percent_define_check_values): Use muscle_percent_define_get_loc. * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype. (muscle_percent_define_get_syncline): Prototype. * tests/skeletons.at (%define Boolean variables: invalid skeleton defaults): Update output for location change. (Complaining during macro argument expansion): Extend to test b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
