[Rd] memory profiling

[Roger D. Peng]

I'm interested in playing around with memory profiling in R-devel (as described 
at http://developer.r-project.org/memory-profiling.html) and was trying to 
figure out how to compile R-devel so that I can use the 'tracemem()' function. 
But I can't figure out how/where to set R_MEMORY_PROFILING.  Is it on the 
configure command line?

Thanks for any help,
