that is a really old version.
But I've found out gawk-3.1.1 contains this bug too (and thus probably
all releases between).

The latest release, 3.1.2, works correctly. (It contain new regex.c.)

I have found out that in gawk-3.0.3 and gawk-3.1.1, it's sufficient to
replace \/ by / so that the range "-/ is recognized correctly:

  	gsub(/[\ \"-/\\:;\[\]\@\?\.\,\$]/, "", $2)

But there is no need to use so many backslashes, I'd use:

  	gsub(/[ "-/\\:;\[\]@?.,$]/, "", $2)
