Well, I tried to just compile it with gdb-6.8 source tree, but gdb-6.8 doesn't support the cegcc target out of the box (not that it should), I tried figuring out how to patch GDB by looking at diffs from cegcc 6.4 gdb and vanilla 6.8 gdb, but to no success. Building with arm-*-wince platforms exculdes 'gdb' directory from being built all together, and I'm not smart enough to understand how exactly am I suppose to fix this.
So, I tried 6.8 gdb for mingw target posted recently (thank you that person), and I was able to successfully debug a cegcc program with it, running gdb server, and specifying remote target. Works fine both over tcp/ip and RNDIS, since RNDIS is tcp/ip :) Can't get info on the threads, or the stack trace of a paused program, but breakpoints and signals (win exceptions) work nicely. Thanks! Pawel.
