More about autoconf 2.63 and ENDIANness

The documents at http://www.gnu.org/software/autoconf/manual/html_node/C-Compiler.html include a section "Macro: AC_C_BIGENDIAN" which describes how universal works. Under the current XEmacs configure scripts the value of AC_C_BIGENDIAN == universal is interpretted to mean that it equals 'no.' This assumption is true true iff the compilation is not leading to a universal binary AND is compiled for INTEL systems. If the target is a ppc, then universal should be considered 'yes.' The problem is compounded by a bit of code in c.m4 which assumes that requesting compilation for a ppc (i.e. -arch ppc or ppc64) means universal, assuming that the caller will understand this value and do further tests. See also http://www.gnu.org/software/autoconf/manual/html_node/autoheader-Invocati... for information on how to configure for this. -- Dr. Robert Delius Royar Associate Professor of English Morehead State University Morehead, Kentucky -S _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
