I can't find such function on my Emacs, is it available only on
binaries built for Windows?

Users are free to do what they want, of course ;-)
`TeX-view-program-list' can be abused as they like, and I think that's
what most users has done so far.

My point is that `TeX-view-program-list-builtin' shouldn't hard-code
an absolute path unless there is a wide-spread standard that it's
unlikely to be broken (and using the portable version of SumatraPDF
breaks the path chosen by the installer).

See my reply to Rasmus, can "start" pass arguments to SumatraPDF to
initiate forward/inverse search?
