Patch to update the included popt to 1.6.4

[Jos Backus]

    http://www.catnook.com/patches/rsync-popt-1.6.4.patch

has a patch which upgrades the popt included with rsync to the latest version,
1.6.4. The configure script had to be regenerated (with autoconf 2.53) because
popt.c wants HAVE_FLOAT_H. As an aside, I have heard people complain about
this version of autoconf generating scripts that break when run under bash (as
/bin/sh).

Comments?
