[Rd] helping out

I have built my own tuned atlas libs enabling multiple processors and  
pthread support.  Then based on the note on page 23 of the "R  
Installation and Administration" manual, I added --disable-R- 
profiling to the configuration options

Unfortunately, the code in R/src/main/eval.c [updated from trunk this  
morning] references the static variable R_Profiling outside of the  
R_PROFILING ifdef which protects it declaration.

One possible solution would be the following.  Of course, you may  
want the static variable to exist all of the time but keep its 0  
value (ie. move its declaration outside the ifdef).

Hope this helps (the patch is only for demonstration purposes since  
you may want a different solution.
