21.5.11 AIX 5.1 database.c compile failure

I'm trying to compile xemacs-21.5.11 on AIX 5.1 and am stuck on this compiler error: % cc -qnoansialias -qmaxmem=-1 -c -O -Demacs -I. -DHAVE_CONFIG_H -I/sup/xpm-3.4k/include -I/sup/zlib-1.1.4/include -I/sup/libpng-1.2.5/include -I/opt/freeware/include -I/usr/X11R6/include database.c "database.c", line 190.2: 1506-343 (S) Redeclaration of lrecord_database differs from previous declaration on line 28 of "database.h". "database.c", line 190.2: 1506-382 (I) The type "struct lrecord_implementation" of identifier lrecord_database differs from previous type "const struct lrecord_implementation". to which I don't see an obvious resolution. In my search for an answer, I only came up with this message that appears to describe the same failure in 1999 compiling xemacs-21.1.2 on AIX 4.3.2: http://list-archive.xemacs.org/xemacs/199905/msg00606.html my configure: setenv CC "cc -qnoansialias -qmaxmem=-1" ./configure \ --with-system-malloc=yes \ --with-gcc=no \ --with-cde=no \ --with-offix=no \ --with-x=yes \ --dynamic=no \ --prefix=$DEPOT/xemacs-21.4.12 \ --with-xpm=yes \ --with-png=yes \ --site-prefixes=$DEPOT/xpm-3.4k:$DEPOT/zlib-1.1.4:$DEPOT/libpng-1.2.5 \ --cflags="-O" Thanks for any suggestions. -Travis
