I worked some more on this and comparing locales and their codesets 
between Solaris 2.6 and 7 I'm reasonably sure that an empty codeset 
value means ascii on Solaris 2.6.
So to ensure proper operation and get rid of the error in the testsuite 
I've added "" as a valid alias for ascii in dangerous_locales().
With this change in place the testsuite runs with no errors.
