[Bug: 21.5-b28] Found cause of --with-union-type error

The error appears to be caused by a bug in the way autoconf deals with WORDS_BIGENDIAN when configure runs on a G5. The resulting src/config.h from autoconf 2.63 places /* #undef WORDS_BIGENDIAN */ in src/config.h whereas 2.62- and 2.61-created configurse add #define WORDS_BIGENDIAN 1 to src/config.h When a 2.62 (or 2.61) created configure runs, it says checking whether byte ordering is bigendian... yes but 2.63 script says checking whether byte ordering is bigendian... universal I have no idea whether those are different answers, but they seem to be. This appears to cause a conflict when --with-union-type is defined from configure. I recreated configure with autoconf (version 2.61 and 2.62) and found that WORDS_BIGENDIAN was defined, and the resulting make worked even with unions used for Lisp_Object. Could this point to the potential for even more subtle bugs Here is the configuration that works fine when autoconf 2.62 is used: ./configure '--with-mule' '--with-widgets=athena' '--with-athena=next' '--with-dialogs=athena' '--with-scrollbars=lucid' '--without-debug' '--without-error-checking' '--with-x11' '--prefix=/Users/royar/usr/local' '--with-png' '--with-jpeg' '--with-tiff' '--with-xmu' '--with-xim=no' '--enable-sound=none,esd' '--disable-xfs' '--enable-dump-in-exec' '--with-modules' '--enable-external-widget' '--with-dynamic' '--disable-kkcc' '--disable-mc-alloc' '--without-ipv6-cname' '--without-ldap' '--enable-optimization' '--with-cflags-optimization=-Os -pipe -mcpu=970 -mtune=970 -mpim-altivec -arch ppc' '--with-xft=emacs,gauges,tabs' '--with-compiler=gcc-4.2' '--with-bignum=gmp' '--with-union-type' 'CC=/usr/bin/gcc-4.2' 'CFLAGS=' 'LDFLAGS=-L/usr/lib -lncurses -lgmp -lz -L/usr/X11/lib -lpng -lXpm -lXft -lXrender -lXmu -lXt -lXext -lX11 -lSM -lICE -lneXtaw -lfontconfig -L/opt/local/lib -ltiff -ljpeg -lesd' -- Dr. Robert Delius Royar Associate Professor of English Morehead State University Morehead, Kentucky _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
