Moved db1/db.h check to the db1 marco in openldap.m4. Also added check for HAVE_DB1_DB_H for which header to include since it's only defined when using db1

Glibc 2.1 has Berkley db as -ldb1. Set up the autoconf to check this first, else we will actually be using compat calls in db2, and not the real db1.

Moved -lnet,socket check for BeOS to the rest of the socket checks. Also added a -lnsl _with_ the -lwrap check since some libwrap's are static and need this.

Added -lnet for BeOS libs. Also need to add some sort of workaround for inet_aton() since BeOS does not have this call.

repackagers is a can of worms.

Sometimes ssl.h is ssl/ssl.h.  This is a simple fix so that it is
detected in those cases, more work is needed to abstract its location
so that programs can be compiled without change.

Moved -u (udp) to -c (connectionless).  Connectionless is depreciated
and undocumented.
Added tests for set{,e}{u,g}id to configure.  Use existance of
setuid/setgid to enable feature.  Use seteuid/setegid only if
they exist.
Fixed minor minor leak of username/groupname if specificied
more than once.  (This should actually be an error)

Cleanup perl detection.

and, if LinuxThreads, pthread_kill_other_threads_np().

(but not sure if it's usable yet).  Needs to be tested on various versions
of Linux native LinuxThreads.

Move select() detection forward, error if not available.
Move select() args type check forward so it can be used in subsequent tests.

Move socket setup to set_socket(), called before the uid/gid change.

no pthread_detach().  So, augment pthread_create() in default libraries
test to detach created thread.

Modify slapd_tester to use pid_t and wait macros.  May need to
implement additional macros in ac/wait.h (in addition to
WEXITSTATUS and WIFEXITED).

(libtool, though, will drag it for it's use...)

libraries.  Original work test is still used to valid detected
header/library are compatible.

the environment.  A more general solution is needed.
