Oh wow. Yep, that's seems to be exactly what happened.  I rebuilt gcc with
linuxthreads enabled, here's the output after doing that:

rich_at_rich-desktop:~/gumstix/gumstixLatest/build_arm_nofpu/staging_dir/bin$
./arm-linux-gcc-4.1.1 -v

Using built-in specs.
Target: arm-linux-uclibcgnueabi
Configured with:
/home/rich/gumstix/gumstixLatest/toolchain_build_arm_nofpu/gcc-4.1.1/configure
--prefix=/home/rich/gumstix/gumstixLatest/build_arm_nofpu/staging_dir
--build=i386-pc-linux-gnu --host=i386-pc-linux-gnu
--target=arm-linux-uclibcgnueabi --enable-languages=c,c++ --enable-shared
--disable-__cxa_atexit --enable-target-optspace --with-gnu-ld --disable-nls
--enable-threads --disable-multilib --with-float=soft --with-cpu=iwmmxt
--with-arch=armv5te --with-tune=iwmmxt --without-fp
Thread model: posix
gcc version 4.1.1

The thread library seems to compile fine:

However, when I go to compile the thread.cpp example (I commented out the
other examples in the Jamfile.v2) in ~/boost_1_36_0/libs/thread/example/, it
errors out:

....etc... I didn't think you needed to see the rest of this.

What do you think is the problem? It's referencing iostream.h ... my using
command is defined as follows:

 using gcc : arm :
/home/rich/gumstix/gumstixLatest/build_arm_nofpu/staging_dir/bin/arm-linux-gcc-4.1.1
:
<cxxflags>-I/home/rich/gumstix/gumstixLatest/build_arm_nofpu/staging_dir/usr/include/
;

Thanks again,
Rich
