Give this a try with a few different input files
Code:
awk '
function PRT()  {TMP = $0
                 for (i=1; i<=MXLN; i++)        {$0 = LINE[i]
                                                 if (MAX[$2] > 1) $2 = "dup_" 0+CNT[$2]++ "_" $2
                                                 print  >  FN
                                                }
                 $0 = TMP
                }


FNR == 1        {if (NR>1) PRT()
                 FN = FILENAME
                 sub (/^(.*\/)*/, "revised_", FN)
                 delete LINE
                 delete MAX
                 delete CNT
                }
                {LINE[FNR] = $0
                 MAX[$2]++
                 MXLN = FNR
                }

END             {PRT()
                }

' OFS="\t" /tmp/test_base.txt

If your awk version doesn't provide the delete array command, replace it by split ("", array).

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.

SEE ALSO

       shtool(1), which(1).
