On a SuSE 6.3 system (glibc 2.1.2, Linux 2.2.13) with i686 I get when running configure with gcc 2.95.2: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .... checking size of short... 0 *** PANIC *** Configure tests are not working - compiler is broken. *** PANIC *** Please examine config.log for compilation errors. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ configure fails since the wrong paths are added with -L. This is a result of parsing /etc/ld.so.conf. Here's the contents of /etc/ld.so.conf for my system: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /lib-aout /usr/X11R6/lib/Xaw95 /usr/X11R6/lib/Xaw3d /usr/X11R6/lib /usr/X386/lib /usr/i486-linux/lib /usr/i486-linux-libc5/lib=libc5 /usr/i486-linux-libc6/lib=libc6 /usr/i486-linuxaout/lib /usr/local/lib /usr/openwin/lib /opt/kde/lib /opt/gnome/lib /opt/gcc-2.95/lib ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Oh, I forgot: this is the current CVS version of XEmacs 21.2.
