I just did "make test-tier1", and got this:

TEST FAILURE


So, it's not DOA, we can  certainly run tests. But I got in total 25 
failures, and it seems likely that these are caused by quirks in the WSL 
environment. I looked at a few arbitrarily selected, and all of them 
where shell tests that had the same failure mode:

ACTION: shell -- Failed. Execution failed: exit code 2
REASON: User specified action: run shell Class-Path2.sh
TIME:   0.098 seconds
messages:
command: shell Class-Path2.sh
reason: User specified action: run shell Class-Path2.sh
elapsed time (seconds): 0.098
STDOUT:
STDERR:
/mnt/c/localdata/hg/sandbox-ALT/open/test/langtools/tools/javac/Paths/Class-Path2.sh: 
34: .: Can't open 
C:/localdata/hg/sandbox-ALT/open/test/langtools/tools/javac/Paths/Util.sh

... which definitely sounds fishy.
