/*
*  This macro is for use by other macros to form a fully valid C statement.
*  Without this, the if/else conditionals could show unexpected behavior.
*
*  For example, use...
*    #define SET_REGS()  st( ioreg1 = 0; ioreg2 = 0; )
*  instead of ...
*    #define SET_REGS()  { ioreg1 = 0; ioreg2 = 0; }
*  or
*    #define  SET_REGS()    ioreg1 = 0; ioreg2 = 0;
*  The last macro would not behave as expected in the if/else construct.
*  The second to last macro will cause a compiler error in certain uses
*  of if/else construct
*
*  It is not necessary, or recommended, to use this macro where there is
*  already a valid C statement.  For example, the following is redundant...
*    #define CALL_FUNC()   st(  func();  )
*  This should simply be...
*    #define CALL_FUNC()   func()
*
* (The while condition below evaluates false without generating a
*  constant-controlling-loop type of warning on most compilers.)
