Ideally the "remote-mips.c" prompt spotting code should be updated to

Browse Source 
spot different prompts at run-time, so as to avoid having target
specific versions of gdb. This is a pending TODO.

Fri Sep  1 08:25:50 1995  James G. Smith  <jsmith@beauty.cygnus.com>

        * configure (mips64*vr4300*-*-elf): Support added.
        * remote-mips.c (mips_readchar): Change to allow build-time prompt
        string.
        * config/mips/tm-mips.h: Added TARGET_MONITOR_PROMPT.
        * config/mips/{vr4300.mt, vr4300el.mt, tm-vr4300.h,
        tm-vr4300el.h}: Added.
