Bonferroni like adjustements for multiple testing apply for any test,
including tests involving dichotomous variables. Some tools for
implementing these tests are available through the undocumented
-_mtest- command, see -help _mtest- (for those who are surprised that
an undocumented command has an helpfile, see -help undocumented-).

Hope this helps,
