I merged with upstream in my hacked repository, and it seems there is
a recursive include of gssapi.h. Maybe this should be re-named
curl-gssapi.h?

And, In a clean upstream pull of c-ares and curl, I see this:

./configure --enable-warnings --enable-debug --enable-werror --enable-ares=/home/greearb/git/c-ares/
....
checking for gnroff... /usr/bin/gnroff
checking how to use *nroff to get plain text from man pages... -man
checking that c-ares is good and recent enough... no
configure: error: c-ares library defective or too old

     xc-translit.m4 fix quoting

Here is the gssapi issue (which could be some problem with my local
hacks, in case no one else sees this).
