* guile-tools.in: Fix the checks to account for non-srcdir builds. * libguile/frames.c: * libguile/objcodes.c: * libguile/programs.c: * libguile/instructions.c: * libguile/vm.c: Fix snarf-includes to cope with non-srcdir builds. * libguile/instructions.h: * libguile/instructions.c: Fix the stubs inclusion to be non-srcdir compatible. * libguile/vm-expand.h (VM_DEFINE_INSTRUCTION): Fix some things so as not to require the instructions.h defintitions, since we have the codes already. Not important tho :) * pre-inst-guile-env.in: Minor tweak that should have no effect. * test-suite/standalone/Makefile.am (all-local): Remove a chmod +x step, the configure.ac rule should do that if necessary.
