great, anyway compilation fails on my machine

crosscorr.c: In function ‘cross_correlation’:
crosscorr.c:170: error: implicit declaration of function
crosscorr.c:170: warning: assignment makes pointer from integer without a cast

BTW, this module should probably stay in `raster/` instead of `vector\lidar`.
