* libguile/programs.h (SCM_F_PROGRAM_IS_BOOT, SCM_PROGRAM_IS_BOOT): Flags for determining if a program is a boot program. It turns out that our heuristics e.g. in stacks.c would catch non-boot programs, like programs that end with (goto/args 1), because the 1 is the same byte as `halt'. That took a while to find... * libguile/stacks.c (stack_depth, read_frames): Use the new boot prog macros. (scm_make_stack): Assert that we read the number of frames that we said we would. * libguile/vm.c (really_make_boot_program): Mark boot programs appropriately.
