dnl PAM module
dnl
dnl FRR detects the PAM library it is built against by checking for a
dnl functional pam_misc.h (Linux-PAM) or openpam.h (OpenPAM) header. pam_misc.h
dnl is known to #include pam_appl.h, the standard header of a PAM library, and
dnl openpam.h doesn't do that, although depends on the header too. Hence a
dnl little assistance to AC_CHECK_HEADER is necessary for the proper detection
dnl of OpenPAM.

dnl This next check looks funky due to a linker problem with some versions
dnl of the PAM library. Prior to 0.72 release, the Linux PAM shared library
dnl omitted requiring libdl linking information. PAM-0.72 or better ships
dnl with RedHat 6.2 and Debian 2.2 or better.
