Subject: Avoid incorrect compiler warning about optlen being used uninitialised
X-Git-Tag: v4.99~21

Avoid incorrect compiler warning about optlen being used uninitialised

GCC 3.4.3 on Solaris 11.1 complains:
main.c:348: warning: 'optlen' might be used uninitialized in this function

It's wrong, and it's obviously wrong. But shut it up anyway.
