The mcore code has, unfortunatly, become very out of date.   The 
mainline hasn't built since 6.2 was released, and with 6.3 past that 
broken code was dropped.  This all came about because GDB's frame code 
was rewritten from scratch and the mcore was never updated to work with 
the new code.

The way to revive the mcore isn't through votes, nominations, or 
appointments, it's through code.  A developer with an assignment 
contributes code to current standards (most importantly does not use 
deprecated interfaces) then it can very easily be re-integrated (and 
they may quickly find themselves in a more responsible role).  Any 
questions on how to do it welcome(1).


(1) Exprerience suggests that largely starting from scratch (using the 
existing code as a guideline) is easier.  This is because the bulk of 
the current file is redundant.
