Hello,
Due to a rather fabulous chain of events, I can't build 4.2.2 with GCC 4.6.1
(which is what we're using in Debian to build packages in unstable)
In a nutshell, it looks like configure.ac completely clobbers CFLAGS under
some circumstances, and adds the -Werror flag. The -Werror flag now seems to
imply -Werror=unused-but-set-variable, and well, there's plenty of that in
the DHCP source :-)
Michael Gilbert was kind enough to provide a cleanup patch to fix 4.2.2, but
it's going to be a nightmare to maintain in Debian. Please consider using it
to clean up your codebase.
Please also consider revising the logic in configure.ac. I'm about to trial
a build with that CFLAGS clobbering logic patched out to see if I can get
the package to build.
Please maintain the Cc line to keep our bug tracking system in the loop

Subject: Bug#643470: isc-dhcp: FTBFS: comapi.c:425:15: error: variable 'status'
set
but not used [-Werror=unused-but-set-variable]
tag 643470 patch
thanks
I've created a patch that addresses all of the unused-but-set-variable
issues. See attached.
Best wishes,
Mike
