The default one is but the user can override it as defined by the C++ standard.
 Also different OS's return different alignment.  Mac OS X (darwin) returns the
16 byte alignment on both PowerPC and x86.  While x86 Linux returns 8 byte
aligned memory.  PPC LV2 returns 16byte aligned memory.  PPC Linux should be
returning 16byte aligned memory for the 128bit long double but from what I
remember or last heard does not.
