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 Note that the configuration order of libraries is in reverse of linkage
dnl for example, linking of the first two is -lc -lnsl.
AC_MSG(LIBRARY FILES)

dnl libnsl/libsocket are needed only on solaris and some svr4 systems.
dnl Using a typical macro has proven unsuccesful, because on some other
dnl systems such as irix, including libnsl and or libsocket actually breaks
dnl lots of code.  So I am forced to use a special purpose macro that sets
dnl the libraries based on the OS.  Sigh.  -Erez.
AC_CHECK_OS_LIBS

dnl librpc and librpcsvc are needed on Solaris (I think)
AC_CHECK_LIB(rpc, clnt_sperrno)
AC_CHECK_LIB(rpcsvc, xdr_fhandle)
dnl Linux RedHat 5.1 puts yp functions only in libnsl (libnsl broken on aix)
AC_CHECK_FUNC(yp_all,,AC_CHECK_LIB(nsl, yp_all))

dnl hesiod library may not link unless libresolv is included
AC_CHECK_LIB2(hesiod, hes_init,,, -lresolv)
AC_CHECK_LIB2(ldap, ldap_open,,, -llber)

dnl Digital UNIX V4.0 and Solaris 7 have POSIX.1c functions in -lrt
dnl Solaris 2.6 only has -lposix4; in Solaris 7, this is a symlink to -lrt,
dnl so only use one of them
AC_CHECK_LIB(rt, clock_gettime,, AC_CHECK_LIB(posix4, clock_gettime))

dnl some systems replaced old ndbm.h include with GNU ndbm.h, which requires
dnl libgdbm for dbm_pagfno, so check for this.
AC_MSG_CHECKING(for GNU ndbm.h)
AC_TRY_LINK([#include <ndbm.h>], [
