Subject: ChangeLog, configure, configure.in:
X-Git-Tag: NTP_4_0_98_J~16
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a82b4eef10e1bd233f1e36f7c67782693dd9b2cb;p=thirdparty%2Fntp.git

ChangeLog, configure, configure.in:
  * configure.in (ac_refclock_chu): Provide the CHU driver by
  default, and by default prefer the AUDIO version.  We used to
  limit this to SunOS or Solaris; now we drive by the availability
  of the audioio header file.
  Select the IRIG and WWV audio drivers the same way.

 	* flock-build: build ignores the -l flag; lose it.
 	(BUILD_ARGS): added.
 	* build: Remove unused -l stuff (LOG variable).
