+gcc-3.0 configured as cross-compiler for Atmel AVR 8-bit RISC
+microcontrollers.
+
+This package includes a basic C++ compiler, although this currently
+is only of limited use (without a libstdc++), and is little tested.

+
+Hi,
+
+This should handle all these 16-bit I/O accesses addressed with
+pointers ("volatile" is required to force writing high byte first
+and reading low byte first in absolutely all cases, even if that
+makes the code less efficient).  The patch is for CVS mainline, but
+should apply cleanly to the 3.3 branch too.  I'm not committing it
+to GCC CVS just yet - please test, I haven't... well, it compiles :)
+
+BTW, mainline currently requires that SEEK_{SET,CUR,END} are
+defined in <stdio.h> - otherwise some new libgcc2.c stuff (unused
+on the AVR, but it has to compile) will cause the build to fail.
+Just edit /usr/local/avr/include/stdio.h to add them manually...
+
+Marek
