Hello ASDF-devs, After pulling all latest commits from ASDF master and thus having a ASDF 3.1.7.19 that git describes as "debian/2%3.1.5-1-514-g7b7b9f0", and patching it with the two attached patches, and using an mkcl from its latest github master head, I then get the following result: -#--------------------------------------- Using /home/jean-claude/CL/MKCL/dev/releases/mkcl-1.1/git/mkcl.git/src/test/asdf/../../bin/mkcl Ran 61 tests: 61 passing and 0 failing all tests apparently successful -#--------------------------------------- ./test/run-tests.sh -c mkcl GOOD: Loading ASDF on mkcl produces no message ./test/run-tests.sh -l mkcl Loading all these systems: ;;; Loading "/home/jean-claude/CL/MKCL/dev/releases/mkcl-1.1/git/mkcl.git/src/test/asdf/build/asdf.lisp" Done!
