broken isinf in math.h

[kaliber]

There is:

# define isinf(x) \
    (sizeof(value) == sizeof(float) ? __isinff(value)           \
        : sizeof(value) == sizeof(double) ? __isinf(value)      \
        : __isinfl(value))

but should be:

# define isinf(value) \
    (sizeof(value) == sizeof(float) ? __isinff(value)           \
        : sizeof(value) == sizeof(double) ? __isinf(value)      \
        : __isinfl(value))
