Known problem in cygwin 1.5.9-1.  Update your cygwin.

We ran into this last month:
http://sources.redhat.com/ml/crossgcc/2004-05/msg00174.html
and it's not happening for me at the moment.  I can't
recall if I have a specific fix for that or not at the moment
(haven't had my coffee yet...)

That seems familiar, too.  See
http://gcc.gnu.org/ml/gcc/2004-04/msg01084.html and
http://sources.redhat.com/ml/binutils/2004-04/msg00646.html
I have the following patches in crosstool that handle

patches/binutils-2.14.92/binutils-m68k-ignore-comments.patch
patches/binutils-2.15.90.0.3/binutils-m68k-ignore-comments.patch
patches/binutils-2.15/binutils-m68k-ignore-comments.patch

(although I guess they're misnamed, since you're running into
this on arm, not m68k?).

It's troubling that this error is back even though crosstool
has a patch that should handle it.  Can you verify that this
patch was applied?  (BTW, -save-temps is a handy option
when tracking this kind of thing down, it'll leave the .s file
around for inspection after the build.  I often take the
command that failed out of the log and put it in a tiny
shell script that sets PATH and cd's to the right directory,
then reruns the failed command.  That lets me add things like
-v and -save-temps, and in particular, it'll let you try out
different binutils without rebuilding all of crosstool.)
