patch 8.0.0158: float funcion test fails on MS-Windows commit https://github.com/vim/vim/commit/6247361101dcccc0c877e90ad67cd0cc83df7c68 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 8 19:25:40 2017 +0100 patch 8.0.0158: float funcion test fails on MS-Windows Problem: On MS-Windows some float functions return a different value when passed unusual values. strtod() doesn't work for "inf" and "nan". Solution: Accept both results. Fix str2float() for MS-Windows. Also reorder assert function arguments.
