I see the following warnings when building 1.7.4rc3 on Solaris10 on SPARC
w/ the Solaris Studio 12.3 compilers.

Some appear to be missing casts for pointer types (as args and in
assignments).
Others seem to be missing prototypes for shm_*(), despite including the
right headers.
In GASNet we found we need to deal with POSIX shared memory as follows on
Solaris:
#if PLATFORM_OS_SOLARIS && !defined(_POSIX_C_SOURCE)
#define _POSIX_C_SOURCE 200112L /* Required for shm_{open,unlink} decls */
#include <sys/mman.h>
#undef _POSIX_C_SOURCE
#elif HAVE_SYS_MMAN_H
#include <sys/mman.h>
#else
....
#endif
