Please be aware, by the way, that if you don't accept the change to the 
top of the file, i'll be forced to go bug RMS/the FSF about it, as I'm 
sure they'd want the code correctly identified as well.

I'm not asking that I be given credit for something I didn't do.  Nor am I 
attempting to diminish in any way the size,quantity, or quality, of 
Jiri's contribution.  I am simply requesting that it be properly 
identified as a derivation of code I wrote.

It's imperative that the lineage of code be correctly identified (in fact, 
if GDB had a legal team, it's the first thing they'd do). In most cases, 
you can determine it from the cvs annotate/the changelogs. However, for 
new contributions, there is no history.  Since I never sent the code 
in question to gdb-patches, it also has no record there.

I only care because I've been getting an increasing number of requests 
from companies wanting to buy the source code to the C++ debugger I wrote 
to replace GDB ( Of course, it uses a variant of the code in question to 
read/execute frame ops).  I blanket refuse such requests in the hopes that 
they'll take the money and pay for GDB work instead, but it's something 
i'd consider if times ever  got really tough.  If there is one thing 
having three rabbits (rabbits  can't learn through negative reinforcement. 
i.e. reprimanding them after they have done something wrong does no good) 
as pets has taught me, it's that it's much easier to make sure a situation 
never happens, than it is to try to do something about it when it 
occurs.

It's not just me, either.  If Jiri/SuSE wanted to license the code to 
someone, he/they  might accidently sign something saying he was the sole 
author, which could make him/them liable, etc.

In short, i'm simply trying to eliminate something that could come back to 
bite me, or others, in the ass, later.

If you really want proof it's my code, I can happily provide this as well.

Since I know you get bogged down in mail, i'll give you till the end of 
the month before I go bug RMS and the FSF about this.
