duplicate between packages

[Marco Atzeri]

Hi Maintainers,

as I just found 2 of my packages colliding with same program name

$ cygcheck -f /usr/bin/ncgen
hdf4-4.2.15-3
netcdf-4.8.0-2

as one is much older than the other, the installation sequence
can give some inconsistencies in the system.

So I checked on my /etc/setup how many duplicates there are
and it seems also other package has the same problem

Some are not an issue, but on the binaries I can not judge

$ cygcheck -f /usr/i686-w64-mingw32/sys-root/mingw/include/pthread_signal.h
mingw64-i686-headers-8.0.0-1
mingw64-i686-winpthreads-8.0.0-1

$ cygcheck -f /usr/bin/t1asm.exe
t1utils-1.39-1
texlive-20210325-1


$ cd /etc/setup
$ zcat *.lst.gz | sed '/\/$/d' | sort |uniq -c | awk '$1 > 1'
