Subject: [PATCH] configure: Check for function from libdb during configure
checking for main in AC_CHECK_LIB is not the right check to find out if
a library exists or not, using a function provided by library is more
appropriate and will help using newer compilers and autoconf in future
Upstream-Status: Submitted [https://github.com/PADL/pam_ccreds/pull/2]
