//  This structure is used to ensure the first counter is properly
//  aligned.  Unfortunately, since PERF_COUNTER_BLOCK consists
//  of just a single DWORD, any LARGE_INTEGERs that immediately
//  follow will not be aligned properly.
//
//  This structure requires "natural" packing & alignment (probably
//  quad-word, especially on Alpha).  Ergo, keep it out of the
//  #pragma pack(4) scope below.
