Experiences on a freshly installed FC3 x86_64:

After CVS update, running ./autogen.sh shows the following problem in
the configure script:

1)
  checking linux/if.h usability... no
  checking linux/if.h presence... yes
  configure: WARNING: linux/if.h: present but cannot be compiled
  configure: WARNING: linux/if.h:     check for missing prerequisite
headers?

 Seems this header on its own doesn't know type 'struct sockaddr', hence
it should include <sys/socket.h> in its test

 The following small patch fixes this:

Trying to compile the nojit version works without any hitches, and it
runs a MacOS 8.0 image which I had previously created without apparent
problems.

Trying to compile after ./configure --with-jit-compiler results in a
problem:

This one will take a bit more time for me to try and understand.
