There are mutiple problems found around verify-db.pl on Solaris... :(

1, I introduced "DB-DIR" macro for template-verify-db.pl.in, but the
corresponding version if create_instance.c hasn't been checked in yet (*
create_instance.c.diff is being attached)
2. template-verify-db.in has the following envirament variable PATH set:
    $ENV{'PATH'} = "$prefix at db_bindir@:$prefix/usr/bin:@db_bindir@:/usr/bin";
    And the derived verify-db.pl on 64-bit Solaris looks like this:
    $ENV{'PATH'} = "$prefix/usr/bin:$prefix/usr/bin:/usr/bin:/usr/bin";
2-1. The problem is db_* utilities on 64-bit Solaris are installed in
/usr/bin/sparcv9, thus verify-db.pl fails to find the executables and exits.
2-2. To get the right path, db4 packaging is supposed to generate db.pc and put
the file in /usr/lib/sparcv9/pkgconfig, but svn:pkgs/db4 spec file does not have
the code (** db4.template.diff is being attached)  Note: the system Berkeley DB
on RHELs has db.pc in /usr/lib/pkgconfig.
2-3. Even though db.pc is placed in the right place, ldapserver/m4/db.m4 does
not check db.pc with pkg-config, but sets the hardcoded path /usr/bin to
db_bindir (*** db.m4.diff is being attached)
3. With all the above fixes, ran verify-db.pl, then one of the Berkeley DB
utilities db_printlog crashed...  The cause of the crash was a field called
timestamp is declared as int32_t, but the pointer to the value is casted to
(time_t *), where time_t is 64 bits on the 64-bit machine.  The cast mismatch
makes ctime/localtime fail and it leads the utility crash.   I looked at the db
4.4.20 code, and verified it was fixed.  I back-ported the change to 4.2.52 and
made a patch since I could not find the patch on the Sleepycat site. (****
patch.4.2.52.txn is being attached)

Change: 
1, I introduced "DB-DIR" macro for template-verify-db.pl.in, but the
corresponding version if create_instance.c hasn't been checked in yet.

svn diff db4.template (** db4.template.diff in Comment #7)

File: svn:rpms/pkgs/db4/SPECS/db4.template

Changes: 
1) added a code to generate db.pc for pkg-config
2) apply a patch to fix the db_printlog crash problem.	The patch proposal is
being attached later (**** patch.4.2.52.txn)

cvs diff ldapserver/m4/db.m4 (*** db.m4.diff)

File: ldapserver/m4/db.m4

Change: To set db_bindir, if db.pc exists, check if bindir variable is defined
in the file or not.  If it's defined, set it to db_bindir.  If not, set the
default path /usr/bin to db_bindir.

Proposed patch (**** patch.4.2.52.txn)

File: svn:rpms/pkgs/db4/SOURCES/patch.4.2.52.txn

Fix Description: The cause of the db_printlog crash was the unexpected cast
from  the pointer to the 32-bit integer to the pointer to time_t/long (64-bit).
 The patch is a back-port from db 4.4.20, where the problem was already fixed.
