This is causing a bunch of warnings with clang:

../wine/dlls/msvcrt/math.c:292:38: warning: implicit conversion from 'int' to 'float' changes value from 2147483647 to 2147483648 [-Wimplicit-const-int-float-conversion]
    if (e == 0xff) return u.i << 9 ? FP_ILOGBNAN : INT_MAX;
                   ~~~~~~            ^~~~~~~~~~~
