gcc-3.2.x is delivering the following type of error messages for certain projects:

g++  -g -DNDEBUG -DSYSCONFDIR='"/etc/xstow"'   -o xstow   arg.o cppdir.o 
debug.o file_option.o format.o main.o setup.o string_utils.o tree.o leoini.o 
setup_config.o
main.o(.rodata+0x8a8):itimerspec/format.h:376: relocation truncated to fit: 
GPREL32 *UND*
main.o(.rodata+0x8ac):itimerspec/format.h:376: relocation truncated to fit: 
GPREL32 *UND*
main.o(.rodata+0x8b0):itimerspec/format.h:376: relocation truncated to fit: 
GPREL32 *UND*
main.o(.rodata+0x8b4):itimerspec/format.h:380: relocation truncated to fit: 
GPREL32 *UND*

These projects compile just fine on x86.  There are further reports of this problem here:

http://lists.debian.org/debian-alpha/2003/debian-alpha-200303/msg00112.html

Apparently certain relocations in the "undefined" section are getting malformed to the point that they overflow.  I seriously doubt they get this way on their own, because the "undefined" section would have to accumulate more than 2GB worth of undefined relocation symbols, which would obviously give x86 fits as well.

Clearly either binutils is malforming offset values during link, or gcc is feeding binutils incorrect relocation values.  The error is consistent and very repeatable.
>How-To-Repeat:
Attempt to compile kdegames-3.1.x or xstow.
>Fix:
No known fix...
