re PR preprocessor/41543 (BUILTINS_LOCATION wrong with -fpreprocessed)
PR preprocessor/41543 * input.h (BUILTINS_LOCATION): Change to 1 from 2. Assert BUILTINS_LOCATION < RESERVED_LOCATION_COUNT. * tree.c: Include intl.h. (expand_location): Handle BUILTINS_LOCATION. * Makefile.in (tree.o): Depend on intl.h. * include/line-map.h (RESERVED_LOCATION_COUNT): Define. * line-map.c (linemap_init): Initialize highest_location and highest_line to RESERVED_LOCATION_COUNT-1 instead of 0. * gcc.dg/debug/dwarf2/pr41543.c: New test.
