:-) Well, then I can strip off your address from the header as well, so
you don't get this mail twice, like I do :-)

That's right. I don't know if the gdb-maintainer will accept such a
change, though.
Maybe I can do it in a less intrusive way with using
#ifdef __sun
cplus_demangle(sun_args);
#else
cplus_demangle(gnu_args);
#endif
on every occurance of cplus_demangle, but IMHO it would be better if the
name of the function would change.

Well, in the simplest case, you would use sed to rename the existing
function
to "gdb_cplus_demangle" and in the implementation body of the function
you'd just add one #ifdef __sun and use the sun version of
cplus_demangle().
If you need more arguments, well, then you have to change every
occurence
of the call as well. We'll see...

I wouldn't expect any great problems here as well.

Could be implemented like this. I'll have to think about this a little
more,
if it makes sense to have this demangling style still switchable even if
we are on solaris. Anybody else got any comments on this?

:-) Same all over. Almost noone want's to get his hands dirty and spend
some
time improving free software. :-) Well, I'll give it a shot next week,
as
time permits. Now off into the weekend ... :-)
