Thanks. Normally, we expect patches to be sent inline instead of as		
attachments, so that we can more easily review the patch. I'm quoting
your patch below for review.

For new packages, we generally like the title to be:

c-ares: new package

> c-ares is a C library for asynchronous DNS requests (including name resolves)

I believe this line is slightly too long, should be wrapped.

This should be wrapped to ~72 columns.

There should be one empty line here.

This line is not needed, as it is the default value.

Is there a file containing the license, to be used for
C_ARES_LICENSE_FILES ?

Did you check that this package indeed builds with a minimal uClibc
toolchain (i.e no IPv6, no thread, no nothing?). You can use the
pre-built toolchain at
http://autobuild.buildroot.org/toolchains/tarballs/br-arm-basic-2013.05-1.tar.bz2
for a minimal toolchain with thread support, and
http://autobuild.buildroot.org/toolchains/tarballs/br-arm11-full-nothread-2013.05-1.tar.bz2
for a toolchain with everything except thread support. Testing with
both should give you a good idea of what your package might be using in
terms of toolchain features.

Thanks a lot!
