 *  IA64 assembler doesn't like C style comments.  This also means we can't
 *  include other include files to get things like the roundup2() macro.
 *
 *  NOTE:  Actual register storage must start on a 16 byte boundary.  Both
 *  setjmp and longjmp make that adjustment before referencing the contents
 *  of jmp_buf.  The macro JMPBUF_ADDR_OF( buf, item ) allows someone to get
 *  the address of an individual item saved in jmp_buf
