Summary: avr-objdump.exe -S switch not working

Initial Comment:
WinAVR release 20071221rc1.
avr-objdump appears to not honour the -S switch for interleaving source code with the machine code in the list file.

Message:
This needs to be reported to the GNU Binutils project at:
http://sourceware.org/bugzilla/

This is not a WinAVR bug. The WinAVR User Manual states that any potential
bugs in GNU Binutils must be reported to the GNU Binutils project and not
here.

Closed as "Won't Fix."

WORKAROUND: Problem occurs for source text with DOS (CRLF) line endings,
but goes away if files are converted to Unix (LF) line endings!

It seems that AVR Studio honors each opened file's EOL convention, so it
should be sufficient to run dos2unix once on the source files.

Interestingly, avr-objdump will show you the correct filename and line
number if you give it the -l option. So it seems to know where the correct
source file is and the correct line number, but just won't get it and
include it in the output.

Have the same Problem witch this new release. Old Version of avr-objdump
(GNU objdump 2.16.1 + coff-avr-patch (20050630)) is working fine. Is this a
special problem if the WINAVR build ?
