Well, yes, but for w32api that would not be logical. At least this
thread has pointed some doco weaknesses that I need to address. Yes, if
you want to use the newer API functions then you must be aware to set
WINVER to the version you wish to support. MS must do this for each
generation of new compilers to support newer OS's. If give the
developer the freedom to not think about backward compatibility, and as
evidenced there is little. We are smarter than that, so we choose to
let the developer set the version h[im|er]self, I.E.: the developer is
forced to think about the new functionality w.r.t. backward
compatibility of older OS versions.

I'm glad to see we agree here.

That is a Cygwin specific change. If you wish to use functions
supported by 0x0500 then Cygwin must specifically redefine the WINVER
constant.

I'll have to look further into this one.
