Description Heiko Nardmann 2005-11-24 14:44:57 UTC 
In file elf/cache.c there is a casting which my lint tool complains about:  
  
186	  cache_new = (struct cache_file_new *) ((void *)cache + offset);  
  
Casting to (void *) and adding an offset is not really clear. Shouldn't it be  
better a cast to (char *) ?

glibc requires GCC and uses many GCC extensions.  void * arithmetic is one of
them.
