You know that the documentation recommends using the Sun linker (and on 
sparc the Sun assembler is fine), so if there are errors, you should 
report them.

Already fixed on trunk, not backported (yet).

Strange, this is expected with gcc-3.4 (although there is a workaround 
in the development version of mpc) but not with gcc-4.6.
