Can't completely get rid of #ifndef FRONTEND in palloc.h :-(
pg_controldata includes postgres.h not postgres_fe.h, so utils/palloc.hmust be able to compile in a "#define FRONTEND" context. It appears thatSolaris Studio is smart enough to persuade us to define PG_USE_INLINE,but not smart enough to not make a copy of unreferenced static functions;which leads to an unsatisfied reference to CurrentMemoryContext. So weneed an #ifndef FRONTEND around that declaration. Per buildfarm.
