[... excuse the necromancy...] Hi Albert (and Reid and David),
This commit is breaking some uses of -fms-extensions on Apple platforms. In particular, Brian and Erik (CC'ed) build against a version of the Windows SDK on Apple platforms. _BitScanReverse is expected to be 32-bit, matching Windows/LLP64, even though long is 64-bit on Darwin/LP64. One idea we've had for fixing this is to use "int" instead of "long" for these intrinsics, either: - all the time, or - when in LP64 mode (e.g., Darwin + -fms-extensions). Any other ideas?
