Hey, Here are some fixes for a few problems with bundles (especially making a prebuilt system library a requirement – i.e sb-bsd-sockets or asdf) and cleaned up the code a bit. Moreover I've enabled load-bundle-op as a default load operation for ECL and its descendants and removed a deprecated function `bundle-system'. Also the "deprecation" comment is removed from `make-build' – IMO it's totally legit function for ASDF and is part of the ECL build system (thereof frequently used). Also I've found a problem with monolithic-dll-op (test-bundle.script) when running tests the second time, but it's not a regression (it was present before this patches). I'll probably investigate it soon. Patches attached below (inlined).
