[GAWK] Exit status, --lint

[Denis M. Wilson]

The exit status of gawk is undocumented, when
gawk exits other than via an exit statement.
E.g. when an error occurs using --lint=fatal.
In that case the exit status is 2 and not
EXIT_FAILURE (1 under glibc). Example:

#!/bin/sh
awk --lint=fatal -f - <<'ENDAWK'
BEGIN {
    print zzz
}
ENDAWK
echo $?

output:
awk: -:2: fatal: reference to uninitialized variable `zzz'
2

I am using Ubuntu 8.4
