Doesn't look like it'll work on SVR4, too many assumptions
about how ioctl's are defined, where they'll be defined and
so on.

The existing script can be made to work with just a little tweak:

--- ioctlent.sh Mon Oct 29 15:32:10 2001
+++ ioctlent.sh.new     Mon Oct 29 15:33:46 2001

        egrep -v "$bad_includes"
 echo xyzzy
 echo "struct ioctlent ioctlent[] = {"

+egrep -v "$bad_defines" ioctlent.tmp |
+awk '{ print "#ifdef " $4; print $0; print "#endif" }'
 echo "};"
 rm -f ioctlent.tmp

It might even be possible to get rid of "bad_defines/bad_includes",
but I don't have other svr4 systems to test it on.
