In init.c I did not define any CONFIGURE_MAXIMUM_POSIX_... items so it 
seem it should use defaults for these (all zero). Yet when I run the 
code it fails due to a large (uninitialized?) value for 
api_configuration->maximum_queued_signals in posixapi.c because 
api_configuration never gets set to &_POSIX_Default_configuration, I think.

So I guess my question is how do you configure a system that will use 
99.99% Classic API and just a little posix?
