A fair point.  The short answer to your question is that no, generally 
gas does not have any default options enabled.  But of course the 
backends can enable options as they wish and they have their own 
selection of options, some of which may be enabled by default.  In order 
to truly answer that question we would need to have a more formal 
approach to command line options, which a data structure associated with 
each option and some way of telling who/what enabled/disabled the option.

Cheers
