Hmm. For the problem I ran into, I wouldn't think of it as recursive macro expansion. Seems to me that it's just a difference in how IFS processing is handled. The following script will show the issue I happened to run into: ftp://eclipse.its.rpi.edu/pub/fbsd/bugs/ifs_bug.sh (that script doesn't have 'make' in it at all, so I suspect you're referring to a different issue than the one I tripped into). The above script "works" under many bourne-like shells, although there is some reason to believe that it should not work (and it does not work under FreeBSD's /bin/sh). --- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu Senior Systems Programmer or drosih@rpi.edu Rensselaer Polytechnic Institute To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
