The man page of XChangeProperty() says:
"If the specified format is 32, the property data must be a
long array."
And as we call it with format 32, the type of 'data' must
be 'long'. It happens to work nowadays in 32-bit architectures
because sizeof(CARD32) = sizeof(long), but that is no longer
true in 64-bit mode.
