dnl SET (shared) library version.  Update it only before major release!
dnl Clarification:
dnl The major number should change when an incompatible change is made to
dnl the API; the minor number should change when an API is added; the patch
dnl level should change when an internal implementation change is made that
dnl does not affect the API.
dnl
dnl In other words: if the major changes, the library is incompatible with
dnl older ones; if the minor changes, the library is backwards compatible
dnl with libraries using the same major; if the patchlevel changes, the
dnl library is backward and forward compatible with libraries using the same
dnl major and minor.
dnl
dnl For sanity, the lower numbers should be set to 0 when a higher number
dnl is changed.
dnl last version info was 3:2:1 (am-utils-6.0.2)
dnl last version info was 4:0:2 (am-utils-6.0.3)
dnl last version info was 4:1:2 (am-utils-6.0.4)
dnl last version info was 3:0:0 (am-utils-6.1, should have been updated)
dnl
dnl We increase the major number for am-utils-6.1, because it has new API's
dnl and removes some old API's.

dnl Check for tcpwrappers
dnl This check is moved this far down because on modern tcpwrapper systems
dnl such as openbsd, the caller must provide two symbols: deny_severity and
dnl allow_severity, which determine the logging level of rejected and
dnl requested requests, respectively.  If this check happens too early, then
dnl $LIBS includes -lwrap, which causes many subsequent tests to fail with
dnl missing symbols.
AC_CHECK_LIB(wrap, hosts_ctl,
[
AC_DEFINE(HAVE_LIBWRAP)
WRAPLIB="-lwrap"
])
dnl replace value of WRAPLIB in specific Makefiles
AC_SUBST(WRAPLIB)
dnl next, check if libwrap defines allow/deny_severity or expects the caller to define it
if test "$ac_cv_lib_wrap_hosts_ctl" = "yes"
then
AMU_CHECK_LIBWRAP_SEVERITY
