Oh, both contexts would have an external script. I thought you'd said:
SHELL) direct popen(SHELL, "WHATEVER")
No SHELL) external popen(CMD, "/c", "tmp.bat")
Okay then, temp scripts regardless.

CMD eats quotes whenever it gets fed an arg, even within a
batch. The batch above, would obfuscate the problem without
correcting anything.
  @echo off
  cmd /c "WHATEVER" "1" "2" "3"
would attempt to run
  WHATEVER" "1" "2" "3

I think you meant
  @echo off
  "WHATEVER" "1" "2" "3"
without the leading CMD, which would exec as written.
