It's true that the arm comment start symbol is '@', but GCC will generate some
assembler code end with a '@' and a comment without a separator so it can't be
parsed by gas.

For example, I compile the libgcc2.c:__gcc_bcmp with xgcc, it failed:
_____________________________________________________________________
/* Like bcmp except the sign is meaningful.
   Result is negative if S1 is less than S2,
   positive if S1 is greater, 0 if S1 and S2 are equal.  */

int
__gcc_bcmp (const unsigned char *s1, const unsigned char *s2, size_t size)
{
  while (size > 0)
    {
      const unsigned char c1 = *s1++, c2 = *s2++;
      if (c1 != c2)
        return c1 - c2;
      size--;
    }
  return 0;
}
_____________________________________________________________________
I'm compile gcc under cygwin and mingw32-gcc, binutils-2.16.1 already compiled
also with --target=arm-wince-pe, here is the gcc(gcc-4.1-20051022)
configuration:
$ ./configure --disable-nls --disable-win32-registry --enable-threads=win32
--host=i686-pc-mingw32 --build=i686-pc-mingw32 --target=arm-wince-pe

I also found that if I made a change in gcc-4.1-20051022\gcc\config\arm\aout.h
(add a semicolon), it will work:
@@ -294,7 +294,7 @@
 #endif

 #ifndef ASM_COMMENT_START
-#define ASM_COMMENT_START "@"
+#define ASM_COMMENT_START ";@"
 #endif

 /* This works for GAS and some other assemblers.  */
