Sorry if I misunderstood, but it sounded more drastic than that, and required
for the code to work compatibly on Windows 32 bit, rather than supporting a
different feature that only worked on Windows 32 bit, as anything
non-Linux/BSD/POSIX can be considered non-essential if support is not
widespread, nor essential for critical packages.
