Is it just me? The configure script for 3.3.1 has (line 75280 et.ff.): ################################################# # check for sendfile support with_sendfile_support=yes { $as_echo "$as_me:$LINENO: checking whether to check to support sendfile" >&5 $as_echo_n "checking whether to check to support sendfile... " >&6; } AFAICT this forces the use of sendfile support. Even though there is a a command line option to turn it off. I can confirm that you need to comment out this line for the --with-sendfile-support=no command line option to work. ----------------------------------------------------------- This e-mail was sent by GlaxoSmithKline Services Unlimited (registered in England and Wales No. 1047315), which is a member of the GlaxoSmithKline group of companies.
