  Yes, there is a bug in GCC 3.4.1 regarding THUMB mode. This has been 
fixed in CVS. I still have been unable to allocate time to release an 
interim version with the proper bug fixes. Most probably it will have to 
wait to 3.4.2 ;^/

  Perhaps uClibc (http://www.uclibc.org/) may fit your needs. It is at 
least more easier to trim than newlib. There is also uC-libc, take a look 
at http://www.ucdot.org/article.pl?sid=02/08/21/1124218
