Quting arguments for perl subprocess

[Lennart Borgman]

I want to do something like

           (setq sts (apply 'call-process prog nil (current-buffer) t 
args))

where prog="perl.exe" and the list args may contain things like

   file=some-file-name.txt

The file name above may contain spaces. Is there a standard way in Emacs 
to quote the file name for this? I believe it would look different on 
different OS:es.
