Summary: curl-config --libs doesn't show required libraries

Initial Comment:
Curl configured with --enable-shared and build with openssl support doesn't list the required libraries.

The bug is in configure.ac line 197 which is:

 if test "X$enable_shared" = "Xyes" -a "X$link_all_deplibs" = "Xno
 then
     REQUIRE_LIB_DEPS=no
 else
     REQUIRE_LIB_DEPS=yes
 fi

IF we build a shared lib and do not link all deplibs, than REQUIRE_LIB_DEPS should be yes.

The problem is that I try to link a static binary, see attached
config.log. In that case I need to know
all libs libcurl.a depends on. Btw, other libraries, e.g. gtk, imlib, are
listing all dependencies.

On many system, -lcurl is all you need to link an app with curl. Linking
against more libraries than that builds a false set of dependencies into
the app--they're not needed by the app itself, only by libcurl. Do you see
an error when you link your app with curl-config --libs right now? If so,
is you app using one of those libraries itself?

$:> curl-config --libs
-lcurl

IMO this should be something like:
-lcurl -lssl -lcrypto -ldl -lz

I recognized this issue while trying to compile darcs, config.log
attached.

Until 7.16.2 curl-config's output is what I expect.

File Added: config.log

Both enable_shared and link_all_deplibs are set by libtool, and the logic
of the above lines looks correct to me. What is the output of curl-config
--libs in your case? What do you expect it to be? And what error do you
see when you link your app with curl-config --libs right now?
