problem bootstrapping gcc 3.4.1

problem bootstrapping gcc 3.4.1

[squirrel]

hey,

i'm trying to bootstrap gcc 3.4.1 with uclibc for an embedded
device toolchain, but i keep getting errors upon the compile.

the relevant lines:

$ tar xfj gcc-3.4.1.tar.gz
$ mkdir build-boot-gcc
$ cd build-boot-gcc
$ ../gcc-3.4.1/configure --target=i386-linux \
  --prefix=/home/squirrel/projects/stb_pbx/toolchain \
  --without-headers \
  --with-newlib \
  --disable-nls \
  --enable-languages=c
$ make all-gcc

any help on fixing this issue is greatly appreciated!  please
e-mail directly or cc me in the reply as i am not on the gcc-help
list.

thank you!
