[M3devel] state of m3gdb on LINUXLIBC6?

[Rodney M. Bates]

Hmm.  I'm not sure what happens here.  It will be the same as the stock
gdb (6.4) from which m3gdb is derived.  I think it has a way of getting
debug info from separate files, but I have never used this.  The m3gdb
changes to gdb don't do anything about this.

I have, a few times, at intervals of two or three years,  forward ported
(back ported? what does one call this?) the Modula-3 changes into newer
gdb releases.  If there is something in the newest gdb that is really
needed, I can do that again, although when I last thought about it
(6.7), there was some target gdb had dropped that we still have in cm3.
