* module/language/Makefile.am: New. * module/language/scheme/Makefile.am: New. * configure.in: Produce these two new Makefiles. * doc/guile-vm.texi: Documented `compile-file', `compiled-file-name', and `compile-in'. * module/system/base/compile.scm: Cosmetic changes. * module/system/base/language.scm: Likewise. * module/system/il/Makefile.am: Tried (and failed) to compile more things. * module/system/vm/Makefile.am: All source files in here can now be compiled without harming further compilation. * module/system/vm/assemble.scm: Select only specific bindings from `(system vm core)'. (dump-object!): Show a more meaningful error message. * module/system/vm/conv.scm: Select only specific bindings from `(system vm core)'. * module/system/vm/debug.scm: Likewise. * module/system/vm/frame.scm: Changed the header. Use a renamer for `(system vm core)'. * src/guilec.in: Added options, via `getopt-long'. git-archimport-id: lcourtes@laas.fr--2005-mobile/guile-vm--mobile--0.6--patch-6
