If I look at the latest config.guess at cygnus CVS then I see that they made the little test program they use to detect the architecture use ansi prototypes. i.e. the XEmacs config.guess has ==== # Determine whether the default compiler is a.out or elf cat >dummy.c <<EOF #include <features.h> main(argc, argv) int argc; char *argv[]; ==== Note the missing 'int' ==== cat >$dummy.c <<EOF #include <features.h> #ifdef __cplusplus int main (int argc, char *argv[]) { #else int main (argc, argv) int argc; char *argv[]; { #endif #ifdef __ELF__ # ifdef __GLIBC__ # if __GLIBC__ >= 2 printf ("%s-${VENDOR}-linux-gnu\n", argv[1]); # else ===== However the XEmacs version is identical to autoconf 2.13. Surely we would have know by now if every autoconf 2.13 based program stopped configuring correctly with gcc 2.95 on redhat. So I suggest you double check your gcc 2.95 install: Jan
