Ok - so this issue is closed as far as this email thread is concerned.

Yes absolutely right. Sorry for taking so long to understand this. I
confirmed it with various calls to the CCL executable itself (using the
full pathname etc).

So the reason we do the (cons "cmd" (strcat "/c " command))  on CCL is
because ccl:run-program requires the executable as a separate argument, and
it would be too convoluted/error-prone to try to parse the executable out
of a string given by the user and call the ccl:run-program with it as a
separate argument. So when the user gives a string argument we just use
"cmd" as the executable. Sounds reasonable enough.

When and if CCL provides a run-program which allows direct command-line
access, as Fare suggests in http://trac.clozure.com/ccl/ticket/1110, then
uiop:run-program will be able to call this version of run-program when
given a string, and just pass the string directly.
