I have a question about the following statement in the dry2 sources:

o No procedure merging

  Although  Dhrystone  contains  some  very  short   procedures   where
  execution  would  benefit  from  procedure  merging  (inlining, macro
  expansion of procedures), procedure merging is not to be  used.   The
  reason is that the percentage of procedure and function calls is part
  of the "Dhrystone distribution" of statements contained in [1].


Does this included library routines as well (strcpy, for example)? The
reason I ask is that ANSI conforming C compilers are allowed to "know"
the names of specific library routines, and generate inline code for
them if it is beneficial.  Are library calls counted as part of the
Dhrystone function call distribution?
