+begin patches/patch-ac:
+This patch removes the  code that tries to figure out  the cache size of
+the host. The  algorithm may very well fail under  some circumstances --
+it  makes too  many  assumptions  about the  cache  behaviour, but  most
+importantly,  the  figured out  values  ARE  NOT  USED anywhere  in  the
+ghostscript code anymore.
