Greetings, In a plugin I wrote I created a function with the following form / function:

$ cat makefile ASDF := something $(timeit 100, ${ASDF}) $ make makefile:2 Time taken: mean: 232, stdev: 81.719765 make: *** No targets. Stop. ... where "timeit" is implemented using the online mean/variance estimate from Knuth's TAoCP. It evaluates the 2nd argument a number of times equal to what the 1st argument evaluates to then spits out a mean / std deviation across those runs. I want to contribute this function back to the make project, however there's a problem if it gets accepted: calculating the standard deviation requires calling sqrt from math.h / libmath. Am I safe to assume that adding a dependence on math.h / libmath isn't an option? -brian
