Summary: curl does not detect cares on mingw

Initial Comment:
I'm building curl for windows in linux, using mingw. I
have build c-ares.
If I configure curl with the following command :

../curl-7.14.0/configure --host=i386-mingw32msvc
--build=i686-pc-linux-gnu --prefix=/opt/xmingw
--enable-ares --disable-shared

it does think c-ares is badly installed, while is
missing the windows library it need to link for network
access.

The problem is that the link command is similar to

gcc test -lws2_32 -lcares

while it should be

gcc test -lcares -lws2_32

and that is due to have in configure.ac, just before
testing c-ares:

LIBS="$LIBS -lcares"

while it should be:

LIBS=" -lcares $LIBS"

well, I used AC_CHECK_LIB to do that, in the patch file
to configure.ac, attached

yeah, I did not understant why you didn't use AC_CHECK_LIB.
Now I know. However, both work to me, so I'm ok with that

Thanks for your patch!

It does however not work properly for the case when you have
cares built in a subdirectory only, which I frequently use
myself.

Instead I suggest the simple:

--- configure.ac 25 May 2005 22:14:32 -0000 1.154
+++ configure.ac 1 Jun 2005 21:27:34 -0000
