Personally, I try to stick to what POSIX guarantees, and avoid using
extensions in any version of awk.

BTW I'm reading this thread in comp.lang.awk. Those reading in
comp.os.linux.misc might be less concerned about portability and
therefore more inclined to use extensions. However, I have come across
Linux systems in the past where "awk" was mawk, not gawk, so if you
use gawk extensions make sure you use the name gawk to run it, not
just "awk".
