System: SunOS small-gods 5.5.1 Generic_103640-12 sun4u sparc SUNW,Ultra-1
Architecture: sun4

>Description:
src/include/krb5/configure.in looks for a temporary directory for
the replay cache by looking on the build machine for /usr/tmp,
/var/usr/tmp, /var/tmp, and /tmp.  This is a really poor order to
look for directories in, since /usr/tmp is a deprecated directory
in both the Linux and BSD filesystem hierarchies and /var/usr/tmp
is Just Plain Weird, whereas /var/tmp is a standard location in
pretty much every modern OS.

>How-To-Repeat:
Build krb5 on a NetBSD machine which has /usr/tmp symlinked to
/var/tmp for compatibility with some broken piece of software.
Then use something built against those libraries on a system
without the compatibility symlink.  Watch yourself lose.

>Fix:
No patch provided, since the build system has changed so much.
Please pull /var/tmp to the front of the search order.

State-Changed-Why:

Ok fixed in current sources.  The main problem would be on
Ultrix-Athena machines that symlink /tmp -> /var/tmp, but that should
really get fixed on the few Ultrix machines we have remaining. :-)
