I see the same on GNU/Linux, so it's not a Windows-only thing.

Seems like a bug to me: mi/mi-parse.c:mi_parse eats up the --all part,
probably in order to handle commands related to all thread groupd, all
inferiors, etc.

Quote it, like this:

  -exec-arguments "--all"

(If the special treatment of --all is not a bug, this should be
documented, including the quoting fire-escape.)
