remote failure reply

[Efim Monjak]

Hi all,

I try to debug a relatively big programm with arm-elf-gdb 6.3.50. After 
a couple of steps I receive a failure message from GDB
about register message. But later the GDB has receive an other register 
message withother failure.
Can you tell me what is hier a problem? As I used GDB 6.1 I have had a 
problem with remote target
depend on Walues in Registers. In this case GDB sent +---+--- .... In 
snapshort 6.3.50 it is fixed.
Possibly it is now a similar problem.

hier is a part of protocoll:

This is why it's traditional to use lowercase hex, not uppercase, in
remote replies.

This is interpreted as an error because it begins with 'E'.

Perhaps it shouldn't be, but for compatibility, I recommend fixing the
stub.
