Concerning the semianalytic case, Lojasiewicz's Lecture Notes quoted above is again the classical reference for local results. The global ones have appeared in the following papers Ruiz J. : On Hilbert's 17th problem an real Nullstellensatz for global analytic functions. Math. Z. 190, 447-459 (1985).

Springer-Verlag LNM 1420, 237-246. Finally, there is an abstract theory of real constructible sets that generalizes both the algebraic and the analytic cases. A symmetric presentation of it is the subject of the forthcoming book.
