[Please Cc me if you wish me to see it] Jerry James writes: No. It wasn't really glibc related either. It had to do with C++ support crap they put in gcc. With an ORDINARY_LINK and the then-current gcc, XEmacs reliably dropped core after dumping calling a (I think) stub C++ constructor. Since the old way worked, the new way did not and I could not make releases with a dysfunctional program the solution was obvious. You're going to screw someone by changing it now, but I would suggest trying it on the major distros and if it works on them, then it would be O.K. If I recall correctly, the GCC version in question is the same version that Red Hat still ships as kgcc, but if it is only being used to compile the Linux kernel and not any libraries, it doesn't matter. The problem may have been due to mixing compilation of libraries between different gcc versions. In that case, it is definitely safe to change it. The fight between Martin and me over this was public and vocal. There should be _something_ in the archives. By the way, I hope someone has already removed the JPEG support in XEmacs. This patent crap makes me want to puke.
