Details:

In the FAQ of Avr-libc at the entry: "How to add a raw binary image to linker
output?" is an example of how to add binary. The documentation tells there are
two symbols generated:

"This will create a file named foo.o, with the contents of foo.bin. The
contents will default to section .data, and two symbols will be created named
_binary_foo_bin_start_ and _binary_foo_bin_end_. These symbols can be referred
to inside a C source to access these data."

I used used this functionality and tried to use the symbols. The linker gave
a warning it couldn't find the symbols. When looking at the .o file it seems
the symbol names are:
_binary_foo_bin_start
_binary_foo_bin_end

Note the missing underscore at the end. I'm not really an avr-objcopy expert,
to say at least, but it seems to me the documentation in the FAQ is not
correct.

I'm using WinAVR 20070525 and avr-objcopy version: 'GNU objcopy 2.17 +
coff-avr-patch (20050630)'
