That number made me look!

In at least some cases you use switch instead of if so, yes, you'll use
a lot of them.  Is that from habit or some design preference?

The example I came across (extractpath) brought up some other issues.
One reason that code build systems are complex is because of the need
for platform specific versions of functions like this.  Since you seem
to be writing Windows-only code it's bound to be a simpler problem.  The
other issue is possible undefined behaviour in the function if it
decrements t past the first byte of an object.
