 I received a patch from Richard Henderson which is now included in
 the mainline gcc to fix this.  It is hard to know which side to blame
 when gcc and gas don't like each other. :)

 Okay.  So the PR can be closed?

 I can't reproduce this.  A build with --target=arm-elf worked fine on my

 The problem is that some of the ARM files are forcibly defining __arm__ in 
 CPP_PREDEFINES.  This is wrong, since it causes longlong.h to define 
 multiplication routines that are invalid for THUMB code.
 
 Please try this patch:
 
 <date>  Richard Earnshaw (rearnsha@arm.com)
 
 	* arm/conix-elf.h, arm/unknown-elf-oabi.h, arm/rtems-elf.h
 	(CPP_PREDEFINES): Don't pre-define "arm" or "__arm__" here.

 Strange - you seem to be getting ARM code despite the `-mthumb' option.  I'll 
 investigate this later today if nobody beats me to it.

 Please try the binutils-2.11.1pre1 archive I made the other day and see if 
 that fixes your problems with 2.11.
