Here are the latest patches that I have posted on the mailing lists.

http://lists.gnu.org/archive/html/avr-libc-dev/2006-05/msg00009.html

These patches are a couple of days old. When patching with today's CVS 
binutils you might have problems with tc-avr.h because one of my bug-fixes 
has been applied recently. The last lines in tc-avr.h should read

#define TC_VALIDATE_FIX(FIXP,SEG,SKIP)                       \
  if ((FIXP->fx_r_type == BFD_RELOC_AVR_7_PCREL              \
       || FIXP->fx_r_type == BFD_RELOC_AVR_13_PCREL          \
       || FIXP->fx_r_type == BFD_RELOC_AVR_LO8_LDI_PM        \
       || FIXP->fx_r_type == BFD_RELOC_AVR_LO8_LDI_GS        \
       || FIXP->fx_r_type == BFD_RELOC_AVR_HI8_LDI_PM        \
       || FIXP->fx_r_type == BFD_RELOC_AVR_HI8_LDI_GS        \
       || FIXP->fx_r_type == BFD_RELOC_AVR_HH8_LDI_PM        \
       || FIXP->fx_r_type == BFD_RELOC_AVR_LO8_LDI_PM_NEG    \
       || FIXP->fx_r_type == BFD_RELOC_AVR_HI8_LDI_PM_NEG    \
       || FIXP->fx_r_type == BFD_RELOC_AVR_HH8_LDI_PM_NEG    \
       || FIXP->fx_r_type == BFD_RELOC_AVR_16_PM)            \
      && (FIXP->fx_addsy))                                   \
    {                                                        \
      goto SKIP;                                             \
    }

Next time better post your mail to one of the mailing lists :-).
