Right I've been working on this and here's what I've found....

With one simple modification your "helloled.c" code can be compiled and
linked without the need for a custom makefile or modified crt0 or linker
script.

The addition is "#pragma stack 0x200,64"

With that added "sdcc -V -mpic16 -p18f452 helloled.c" is all that is
needed to produce a helloled.hex.  I havn't got my programmer working
with 18F devices yet, but the compiled code "does the right thing" when
run with gpsim.

I think it is better to document the simplest case first and include any
variations in the following sections of the document.
