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.
