Subject: [PATCH] Clean up some of the fallout from the Solaris patch - mostly
 configure script breakage.  In particular, disable the sendfile() check, as
 Solaris doesn't have a working sendfile() any more than Linux does. 
 Actually, the Solaris sendfile code was never compiled or used, because the
 #ifdefs in cache_pool.c were all wrong.
