The following one-line change silences some longstanding noise in  
mail/qmail, caused by the fact that its ${DISTFILES} is also a common  
${PATCHFILES}, resulting in the file being listed twice in $ 
{_ALLFILES}. What the noise looks like (similar for other targets,  
pkg_chk, etc.):

$ cd pkgsrc/mail/qmail
$ make clean
make: "/home/build/trees/pkgsrc-current/mk/fetch/fetch.mk" line 133:  
warning: duplicate script for target "/home/build/trees/pkgsrc- 
current/distfiles/netqmail-1.05.tar.gz" ignored
make: "/home/build/trees/pkgsrc-current/mk/fetch/fetch.mk" line 133:  
warning: using previous script for "/home/build/trees/pkgsrc-current/ 
distfiles/netqmail-1.05.tar.gz" defined here
===> Cleaning for qmail-1.03nb11
$

Do people agree that this safe to commit?
