Attached is a patch to fix the mb linking problems on AIX. As a nice side effect

it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so
(all shlibs that are not postmaster loadable modules).

Please apply to current (only affects AIX).

The _LARGE_FILES problem is unfortunately still open, unless Peter
has fixed it per his recent idea.

 On AIX 4.3.2 PostgreSQL compiled with the native IBM compiler xlc

 Compiling PostgreSQL with gcc (2.95.3) on AIX also works.
 Use the configure flags: --with-CC=gcc
 
+You need libm.a that is in the fileset bos.adt.libm (try following command)
+$ lslpp -l bos.adt.libm

 Since the mktime() function does not work on AIX for dates before
 1970, all localtime formatted datetimes will not use summer time for
 dates before 1970.
