Well, I went to look at the cvs for emacs and I found the following link with the notable excerpt:
http://cvs.savannah.gnu.org/viewvc/emacs/emacs/etc/MACHINES?revision=1.24&view=markup ---BEGIN--- X86_64 GNU/Linux No special procedures should be needed to build a 64-bit Emacs. To build a 32-bit Emacs, first ensure that the necessary 32-bit system libraries and include files are installed. Then use: env CC="gcc -m32" ./configure --build=i386-linux-gnu \ --x-libraries=/usr/X11R6/lib (using the location of the 32-bit X libraries on your system). ---END--- It seems to me that this would just build a 32-bit version of emacs on a 64-bit system, which is probably fine. If this is the case then it could just be a slight modification of the spec file based on a platform case statement. If somebody else doesn't get to trying this out before me, then I'll likely test this out in the near future. On Thu, 2007-05-31 at 14:54 -0700, Doug Summers wrote: > David M.
