Fixing NO_WRIVEV

David,

Could you (or someone else) who is on a legitimate platform which does
not support writev() check if this is functional ?

Note that I also found I had to make the #ifdef/#if defined()s to make
things comply across the board.

I've tried both with and without SSL and with/without WRITEV on bsd and
solaris - but obviously 'faking' the four permutations.

Cheers,

Dw
