commit 536103221911692d546d7325435812c29bb32ff1 Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jul 3 10:59:31 2017 -0400 Fix -Wfloat-conversion C warnings on mingw in clamp_double_to_int64. We just have to suppress these warnings: Mingw's math.h uses gcc's __builtin_choose_expr() facility to declare isnan, isfinite, and signbit. But as implemented in at least some versions of gcc, __builtin_choose_expr() can generate type warnings even from branches that are not taken.
