IMPORTANT!!!
============

The include directory has been restructured with version 0.50.1 (see NEWS).  
Make sure that you delete the following files from all your system include
directories:

cookie.h, dcntl.h, dir.h, file.h, ioctl.h, ssystem.h, param.h, stat.h, 
statfs.h, sys/restoresys, timeb.h, times.h, utsname.h.

Not deleting these files will result in unpredictable results when
compiling code with the new library.
