Indeed, and that's why I'd like not to do it unless strictly necessary.
I don't remember why I did it on allegro — that's probably a mistake;
I probably did it because otherwise there might be no searching through $PATH.
How does the test work on Allegro if you remove the prepending of cmd /c ?

Robert: on Windows, the legacy interface is to pass a string to the program,
to be interpreted as multiple arguments by the program itself, which
it typically does
through the standard C++ library, but might not. However, for backward
compatibility
reason, the command interpreter doesn't use said library, but
interprets the line
its own way, which may or may not (hopefully will) lead to the same behavior
on properly escaped command lines such as the Lisp implementation will issue.
