Subject: Resync src/cf/gssapi.m4 with rra-c-util 3.3 (fixes OpenBSD)
X-Git-Tag: upstream/1.8.0_pre1^2~3783
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=4d6d5dfb60feb3fdbf4ac7b035730859eb7fb89e;p=packages%2Fo%2Fopenafs.git

Resync src/cf/gssapi.m4 with rra-c-util 3.3 (fixes OpenBSD)

Resynchronize src/cf/gssapi.m4 with rra-c-util 3.3.  This includes
the following fixes:

* Handle the Heimdal GSS-API library on OpenBSD, which does not have
  a separate libroken.  Thanks to Antoine Verheijen for the analysis.

* Search /usr/kerberos/bin for krb5-config even if that isn't on the
  user's PATH to find krb5-config on some Red Hat versions.

* Use [] to mark empty arguments to Autoconf macros.

* Add an explicit license (matching the normal Autoconf macro license).
