Just yesterday I was trying to get the macutils package built (http://www.ibiblio.org/pub/Linux/utils/compress/macutils.tar.gz http://www.ibiblio.org/pub/Linux/utils/compress/macutils.tar...) and wishing they had used autoconf instead of ad hac #ifdef'ing for each arbitrary environment they had encountered - which never happened to be standard C. The package is apparently unmaintained, and if it weren't for tracking down the license provenances(!), I'd be tempted to apply some autoconf love. Varnish guy also left HP-UX off his list of still-kicking Unix implementations. The continuing exponential growth of computer use hides the fact for many that there are still an enormous number of "non-mainstream" systems still in essential use. Within the last couple weeks, someone on the autoconf list just asked for help supporting AS400. Kids these days. Sheesh. ;-)
