This is confirmed to work with changes (you actually need v8plus, but
gcc didn't grok that, so I used ultrasparc instead), and with Peter's
include guard changes this looks like a solid solution.

Here are test results for shared_ptr_mt_test and weak_ptr_mt_test
using sp_counted_base_gcc_sparc. I've run tests in both 32 bit
(sparcv8plus) and 64 bit (sparcv9) flavours.

These tests were run on a dual CPU Sun Fire 280 (2x750MHz UltraSPARC
III) which is so old it's already desupported by Sun...

[michael_at_hawk test]$  uname -a; g++ -v

Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.3/specs
Configured with: ../configure --disable-nls --with-as=/usr/ccs/bin/as

Thread model: posix
gcc version 3.3

Anyway, test results appended.
