 The primary patch, `configure.patch`, includes a regenerated `configure`
 script.  The M4 source file changes are in `perl.patch` and `openssl.patch`.

-The include Perl module, `NTP::Util`, does not work completely correctly with
-the version of the `Socket` module that ships in the platform Perl
-distribution.  Specifically, the version string is `"1.87_01"`, which emits a warning:
-
-    Argument "1.87_01" isn't numeric in numeric ge (>=) at

-This patch makes us assume an old version of `Socket`, which is what we ship,
-and prevents the warning from being emitted.  This is tracked upstream as [ntp
