bootstrap gcc still not thread-smart -- the details

["Robert P. J. Day" <rpjday at mindspring dot com>]

   ok, based on mike's advice so far, here's the story.  first, the
sample source file mike sent to try to compile:

extern __thread int i;

int main() {

  return 0;
}

  after i build my bootstrap gcc, here's the result (running from
within the gcc-core-prefix directory):

$ ./*gcc -c /tmp/thread.c
/tmp/thread.c:1: error: thread-local storage not supported for this
target

  ok, so now we know i don't have thread support.  here's the stage of
my script that builds the bootstrap gcc:

        cd ${BUILD_DIR}/build-gcc-core
        ${GCC_SRC_DIR}/configure \
                --host=${HOST} \
                --target=${TARGET} \
                --prefix=${CORE_PREFIX} \
                --with-local-prefix=${SYSROOT_DIR} \
                --with-sysroot=${SYSROOT_DIR} \
                --without-headers \
                --without-libs \
                --disable-multilib \
                --with-newlib \
                --disable-nls \
                --disable-shared \
                --enable-threads \
                --enable-symvers=gnu \
                --disable-__cxa_atexit \
                --enable-languages=c

        make all-gcc install-gcc

and here's the bootstrap gcc and its build options:

Using built-in specs.
Target: sh3eb-unknown-linux-gnu
Configured with: /home/rpjday/unpack/gcc-4.0.2/configure
--host=i686-pc-linux-gnu --target=sh3eb-unknown-linux-gnu
--prefix=/home/rpjday/results/sh3eb/build/gcc-core-prefix
--with-local-prefix=/home/rpjday/results/sh3eb/tools/sh3eb-unknown-linux-gnu/sys-root
--with-sysroot=/home/rpjday/results/sh3eb/tools/sh3eb-unknown-linux-gnu/sys-root
--without-headers --without-libs --disable-multilib --with-newlib
--disable-nls --disable-shared --enable-threads --enable-symvers=gnu
--disable-__cxa_atexit --enable-languages=c
Thread model: posix
gcc version 4.0.2


  i really don't know as much about threads as i would like so it may
be that there's something obviously stupid about what i've done.  is
"posix" the right thread model for the bootstrap gcc?  have i missed a
critical option somewhere?

  sorry to drag this out but i *really* want to get this working.
