I noted that on the list a couple of days ago,
and it's due to the ASSIGN_STRDUPA macro.
I agree that it's not worth warning about.
Note it should only be an issue if your CFLAGS has -fstack-protector enabled,
like the coreutils build on Fedora 11 for example:
$ rpm -q --qf %{OPTFLAGS} coreutils
-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m32 -march=i586 -mtune=generic
-fasynchronous-unwind-tables -D_GNU_SOURCE=1
cheers,
Pádraig.
