jw@suse3:~> awk --version
GNU Awk 3.1.0


jw@suse3:~> awk -f `perl -e 'print "A" x 1022'` 
awk: fatal: can't open source file `AAAAAAAAAAAAAAAAAAAAAAAAA
<snip many AAAs>
AAAAA' for reading (File name too long)


jw@suse3:~>  uname -srm;awk -W version|head -1;awk -f `perl -e 'printf "A" x 8177'`;

Same error: <snip> AAAAA' for reading (File name too long)
