All, Just to close out this thread, I've discovered the process is very similar, just completely undocumented (someone needs to beat someone over the head with doxygen, or even put a comment in the stdio.h file, something! anything!).
If you ever find yourself in this situation: * google WinARM (even for unix users - you are stealing code, not installing it) * download WinARM and unzip it somewhere * search the <unzip>/examples directory for syscalls.c and serial.c * modify them for your processor/pcb * compile/link with them * note that "iprintf()" on ARM is the rough equivalent of specifying one of the watered-down vsprintf's in your makefile for AVR. * note that if you find "rprintf()" in the code you are looking at, move on to another example - rprintf appears to be the defacto standard on ARM for anyone who wants to write a 'fake' printf function with no stdio.h or libc.a linkage. * beware that the syscalls.c file has a comment mentionins that it was adapted from Keil's gcc toolset, and so may have unpleasant copyright strings attached, even though none are mentioned specifically - I am looking into it myself. That's what I've found. Hope it helps someone else. Note that gnuarm also requires a crt0.S file and .ld scripts in addition to a makefile to generate a usable .hex. You might steal those from WinARM while you are at it. Note they usually need customized as well - no nice coordinated efforts like avr-libc to make everything work "out of the box".
