I found this answer myself:  section 3.3.2.2 says:

	The order of evaluation of the function designator, the arguments,
	and subexpressions within the arguments is unspecified, but
	there is a sequence point before the actual call.

Thus all side effects in the function name and/or arguments must take place
before the call.

  I forsee a day when there are two kinds of C compilers: standard ones and 
  useful ones ... just like Pascal and Fortran.  Are we making progress yet?
