Separately from Torsten's answers, as an appendix.

No, they will not just be discarded to /dev/null.

The "main" part of the configuration (outside of <VirtualHost> sections), acts as a
of default values, inherited by all VirtualHosts.  A <VirtualHost> /may/ override any

parameter with its own value, which takes precedence.  But it does not have to.

Error messages may end up in the system's SYSLOG logs, depending on how the Apache startup

script of your system configures things (like in /etc/init.d/apache2 or so).  The 
imagination of Linux package creators is boundless..
Check /var/log/daemon.log and similar.
