  (abridged) The 68000 I-band light curves of variable stars detected by the
OGLE survey in the Large and Small Magellanic Clouds (MCs) are fitted by
Fourier series, and also correlated with the DENIS and 2MASS databases and with
lists of spectroscopically confirmed M-, S- and C-stars. Lightcurves and the
results of the lightcurve fitting (periods and amplitudes) and DENIS and 2MASS
magnitudes are presented for 2277 M-,S-,C-stars in the MCs. The following
aspects are discussed: the K-band period-luminosity relations for the
spectroscopically confirmed AGB stars, period changes over a timespan of about
17 years in a subset of about 400 LPVs, and candidate obscured AGB stars.
