Thanks for your new patches.

ok. Thanks again.

I've build the binutils snapshot 060603, the gcc 060603 with your patch6
and avr-libc with patch6 this morning. It works now. Both printf
(avr-libc) and rprintf (avr-lib) works like expected. I've used the pmem
and the ram variants. No more problems. For now ;-)

The generated code seems to be ok. The installation of the patched
avr-libc doesn't install the new headers. Shouldn't you add them at
avr_HEADERS in include/avr/Makefile.am?


The headers from Anatoly's post use FLASHEND 0x1FFFF (as for the
Mega1280). For the Mega2560 it shouldn't it be 0x3FFFF?
