If you have old-style lint (v7, 4.2bsd), you may have
noticed as I have that the output from pass2 is a
jumble. After years of living with this, it dawned on
me that I could fix it without source. I modified the
/usr/bin/lint shell script to run pass2 through a new
filter called lint3 (which is also a shell script).
And here they are now:
# This is a shell archive. Remove anything before this line, then
# unpack it by saving it in a file and typing "sh file". (Files
# unpacked will be owned by you and have default permissions.)
#
# This archive contains:

echo x - usr/bin/lint
cat > "usr/bin/lint" << '//E*O*F usr/bin/lint//'
#! /bin/sh
