Can't bootstrap/build gcc-3.0 un debian 2.2 r3 sparc l

[Christian Jönsson <c dot christian dot joensson at telia dot com>]

Wheb I try to bootstrap the gcc-3.0 suite on a debian 2.2r3 gnu/linux 
sparc 5 system, it stops with the following problem:

Adding multilib support to Makefile in ../../../gcc-3.0/libstdc++-v3
multidirs=
with_multisubdir=
running mkc++config
running mknumeric_limits
/home/chj/objdir-gcc-3.0/gcc/xgcc -B/home/chj/objdir-gcc-3.0/gcc/

instruction     "$BUILD_DIR/src/gen-num-limits" >>$OUT_H-t

mknumeric_limits failed to execute properly: exiting
make[1]: *** [configure-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/home/chj/objdir-gcc-3.0'
make: *** [bootstrap] Error 2

the config.status contains this:

../gcc-3.0/configure 
--with-gcc-version-trigger=/home/chj/gcc-3.0/gcc/version.c
--host=sparc-unknown-linux-gnu --enable-shared --enable-threads=posix 
--norecursion

Any ideas of what is going on?
