------- Comment #9 from howarth at nitro dot med dot uc dot edu 2010-04-12 03:25 ------- I confirmed with the dsymutil maintainer that my reading of his response was correct. Indeed, the warning may or may not be significant and has to be checked for each instance. So if all four test cases are actually emitting valid dwarf, we can drop the usage of -lm on darwin[921] (although we will have to add a dg-prune-output to eliminate the failures from these false warnings.
