OK, now I am really confused. 

I went to rpmfind (http://rpmfind.net/linux/RPM/fedora/updates/9/x86_64/dhclient-4.0.0-22.fc9.x86_64.html) to get the dhcp src rpm and downloaded it. It comes from ftp://download.fedora.redhat.com/pub/fedora/linux/updates/9/SRPMS.newkey/dhcp-4.0.0-22.fc9.src.rpm

When I ran rpm -qp on the downloaded rpm I get this:

$ rpm -qp dhcp-4.0.0-22.fc9.src.rpm
dhcp-4.0.0-22.fc9.ppc

ppc?!!? Is this the correct rpm?

I installed the rpm anyway
# rpm -iv dhcp-4.0.0-22.fc9.src.rpm

which created, amongst other things /usr/src/redhat/SOURCES/dhcp-4.0.0.tar.gz
I unpacked:
# gunzip -cd dhcp-4.0.0.tar.gz | tar xvf -
which created a /usr/src/redhat/SOURCES/dhcp-4.0.0 directory. I cd'd to the directory and ran
# ./configure
which ran with no errors
# grep -R GNU_SOURCE *
#

No mention of GNU_SOURCE anywhere.
I'd be interested to see if anyone can reproduce these results.

Mamoru, how did you get that info you posted from the src rpm?
