Subject: Add conditional code to initialise RETVAL, to avoid compiler warnings.
X-Git-Tag: accepted/trunk/20130322.191538~13067
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19c4478c878cb3732a73314cc162df7f808d5d78;p=platform%2Fupstream%2Fperl.git

Add conditional code to initialise RETVAL, to avoid compiler warnings.
(There was never an error, as croak() was called before the return).
