It would be great if a compile time option for umask_override was available.  Currently, you can configure sudoers to use umask_override by adding a default option to the sudoers, however this is not backwards compatible with older versions of sudo. 

This provides a catch-22 for phased upgrades of sudo, and results in a situation where both sudo and sudoers would need to be forklift upgraded. 

This seems like a relatively simple compile-time option to add, and would provide the ability to do phased upgrades of sudo for users who have older versions of sudo.
