Walter's point, I believe, is that you should define a meaningful version  
identifier for each specific case, and that this is "better" because then  
you're less concerned about where it's supported and more concerned with  
what it is which is/isn't supported.

Maintenance is very slightly better too, IMO, because you add/remove/alter  
a complete line rather than editing a set of || && etc which can in some  
cases be a little confusing.  Basically, the chance of an error is very  
slightly lower.

For example, either this:

version(X86) version = MeaningfulVersion
version(X86_64) version = MeaningfulVersion
version(PPC) version = MeaningfulVersion
version(PPC64) version = MeaningfulVersion
version(ARM) version = MeaningfulVersion
version(AArch64) version = MeaningfulVersion

version(MeaningfulVersion)
{
}
else version (MIPS32)
{
}

or this:

version (X86) version = MeaningfulVersion
version (X86_64) version = MeaningfulVersion
version (PPC) version = MeaningfulVersion
version (PPC64) version = MeaningfulVersion
version (ARM) version = MeaningfulVersion
version (AArch64) version = MeaningfulVersion

version (MIPS32) version = OtherMeaningfulVersion

version (MeaningfulVersion)
{
}
else version (OtherMeaningfulVersion)
{
}
