The problem is that mdebug isn't really tied to ECOFF. IIRC, the GNU tools used to emit some basic mdebug code, and people used to add assembler directives that would emit mdebug frame info. That code was useful for getting proper backtraces through code that didn't have stabd/dwarf debug information. Did you verify that GDB is still useful on an Alpha systems after this removal?
