Subject: * Added autoconf check for getutent().
X-Git-Tag: kim-before-sasl~22
X-Git-Url: http://git.marmaro.de/?p=mmh;a=commitdiff_plain;h=522138c8d86c20435f045eaee0944a9b008b1c5a

* Added autoconf check for getutent().
* Changed uip/rcvtty.c and uip/slocal.c to use getutent() and
  friends.  Since I can only check on Linux, please check if
  this works on other systems.
