Would this help?

For older PCRE's:

# for http
server { listen 80; server_name ~^www\.(?P<domain>.+)$; return 301
$scheme://$domain$request_uri; }

#for https (change 'sslcert' for your own certificate name)
server { listen 443 ssl; server_name ~^www\.(?P<domain>.+)$;
ssl_certificate /etc/ssl/certs/sslcert.crt;
ssl_certificate_key /etc/ssl/private/sslcert.key; return 301
$scheme://$domain$request_uri; }

For newer PCRE's:
Instead of ?P<domain> use ?<domain>

# Note: in 'return XXX' 301 is like rewrite...permanent and
302 like rewrite...redirect
