fix bug in self-tail-recursion with "external" variables; other sundries
* gdbinit (pp, inst): New commands. * libguile/vm-engine.c (vm_error_not_a_pair): New error case. * libguile/vm-i-scheme.c (VM_VALIDATE_CONS): New macro -- use this instead of SCM_VALIDATE_* because SCM_VALIDATE will exit nonlocally before we have a chance to sync the regs. (car, cdr, set-car, set-cdr): Use VM_VALIDATE_CONS. * libguile/vm-i-system.c (goto/args): Bugfix: when doing a self-tail-recursion, allocate fresh externals. Fixes use of match.go. * module/system/vm/assemble.scm (dump-object!): Add some checks that we aren't dumping out values that the VM can't handle. * module/system/vm/disasm.scm (disassemble-externals): Fix rotten call to `print-info'. * oop/goops/dispatch.scm: Add a FIXME. * testsuite/Makefile.am (vm_test_files): * testsuite/t-closure4.scm (extract-symbols): New test, distilled with much effort out of match.scm. * ice-9/Makefile.am (NOCOMP_SOURCES): Re-enable compilation of match.scm. Yay!
