The June 2019 snapshot has been tagged. Binaries will be uploaded soon. Only a few changes here: * Updated to latest ASDF (3.3.3) * Updated clx to use the latest upstream version * Added x86_linux_clang config file to build with clang on linux * Gcc 8+ can't build cmucl correctly. A workaround is used by compiling the run time with -O1 instead of -O2. Hope this is useful.
