In version 3.2.2 we corrected the sign of the orientation primitive
for points and segments. This required changing all programs using
these primitives, in particular the SWEEP_SEGMENTS function that is
used when testing polygons for simplicity. By accident the old version
of _sweep_segments.c was put into the new distribution. A corrected 
version of the sweep program is now available from        ftp.mpi-sb.mpg.de:/pub/LEDA/FIXES-3.2.2/_sweep_segments.c  
To fix the bug you have to download this file, copy it to 
<LEDA>/src/plane_alg, touch _float_sweep.c and _rat_sweep.c, and 
rebuild libP.a by running "make".
