If I recall it correctly, the
  check_one (interpreter, prog, "*");
case failed: Apparently, when you pass a single unquoted '*' argument
to CreateProcess, it can fail with GetLastError() = ERROR_PATH_NOT_FOUND.

Oh sh*t, they're doing the globbing in the callee, rather than in the
caller! This is terribly wrong.

It is
  $ ./configure (with the appropriate options for mingw, depending on your
  $ make
  $ make check
  or (for just the single test)
  $ cd gltests
  $ make check TESTS=test-system-quote.sh

If you get a failure, it's useful to comment out some of the lines
  check_all (SCI_SYSTEM, true, prog); /* equivalent to SCI_WINDOWS_CMD */
  check_all (SCI_WINDOWS_CREATEPROCESS, false, prog);
  check_all (SCI_WINDOWS_CMD, true, prog);
in gltests/test-system-quote-main.c.

The test-system-quote.sh script should be run through bash. It doesn't
matter how this bash is invoked.
