[Openmcl-devel] flexible 32/64 bit CCL apps

Our testers are complaining about a 64bit version of a CCL64 based app not running on 32bit only Macs (e.g., 10.6.8 10K540, iMac Core Duo/1.83 GHz). A simple solution is, of course, just to create a CCL32 bit version instead which will work fine but does have some disadvantages. The testers prefer "the real deal" which would be a fat binary with 64/32 versions combined and user control, via GetInfo dialog to switch back to 32bit mode:

I do vaguely remember that we did have discussions about fat binaries a long time ago but if memory serves right this was about PPC/Intel which by now is no longer an issue. Has anybody succeeded at this, are there, ideally Lisp wrapped up, tools for this? 

best,  Alex
