That option is normally not needed. It defaults to ${prefix}/bin,

I actually used that Makefile with WinAVR before and it always worked. I
tried it with the broken installation and it did not make any

Looking at the schematic for the Butterfly, it's not readily apparent how it
manages to translate levels for outbound data. The docs seem to say it's
supposed to work, but my primitive understanding of electronics matches the
results: non-receipt of transmitted data. It could also be my

Well, it's a bit tricky, but it can be seen.

Thanks. The pin is completely dead when I probe it with a scope. It can
hardly be hardware in this day and age. Right?
The gcc-port code looks as follows. Connection settings on the PC are 19200,
8N1, no handshake. Receive works just fine, else I wouldn't be bothering you
with it. I know for
Having solved all that, I wanted to add an auto-incrementing build
number to the build process, which lives in program memory. Here's how I
did it:
I made a buildnumber file, as follows:
