Hmm, you learn something every day. 

I am very familiar with several gdbserver JTAG type debug environments
(mostly bare metal), where this feature is *NOT* supported. I have spent
very little time in the linux based gdb-server, hence my ignorance of
this feature.

always compiled in. 

Yes, that is quite a different environment then my background. 

Paul @ Dell - brings up another point - security/access control to the
GDB stub feature. 

In your case "compiled-in-gdb-stub" is a product requirement, and/or
product feature. 

In the space constrained world (ie: micro controller, and/or bare-metal)

(1) you often don't have code/ram space for items like this, 
(2) for performance reasons, this code must be removed
(3) There is no support for this in the underling operating system (if
there is one)
(4) Or the GDB server exists external to the target (ie: JTAG)

Each of us come from different backgrounds.
