	adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however

* ACL Group functionality is also included in this merge!

Fixed Dependency Generation not to mess with Make-templates.
	side effect: depends are not carried forward after "make makefiles"
