Shmem was only tested with gcc/mingw and msvc although it shouldn't have 
many problems with other compliant compilers. Unfortunately I have no 
access to the SunPro compiler so I'm afraid I can't do much to solve 
your error.

Anyway, I recommend you to use Boost.Interprocess, since Shmem has 
morphed into Interprocess after the review process. It's in the 
Vault/Concurrent Programming directory and also in the Boost CVS. You 
surely will have problems with SunPro, but Shmem is just in maintaining 
mode, whereas all my efforts are now in Interprocess.
