Thanks, it looks like that is the best bet, but so far I haven't been
successfull there either :-). It looks like sdcdb won't run under Cygwin
and the simulator (which seems to be happy with Cygwin) doesn't produce any
output to a file when putchar is writing to the UART. Looks like I get to put
SDCC on a Linux or FreeBSD box and try on there ... If I get something working
I'll send a howto to the mailing list for the next poor soul :-).
