--- Comment #5 from Jay <jay.krell at cornell dot edu> --- I confirmed. Here is what you can. Build out of tree, of course. cd fixincludes make check while it is printing "fixed...", press control-c ls tests/inc You will see a directory named "*". Creating this works on Mac and presumably Linux, but not WSL. Because like I said * doesn't match anything, so goes through on its own. This stuff does a good job of hiding what it is doing and deleting its tracks btw. It helps to remove the >/dev/null in check.tpl/check.sh. And set -ex in the parenthesized chunk near the top. WSL should try to support this, I guess, but it is a little wonky. Seems maybe an accident here. Maybe it is for in-tree builds? I also see a directory named "sun*" that might cause grief.
