no. You should not add any libs into the mingw32 lib directory but
instead point the compiler/linker with -L to the right path (as you can
see that the Makefile.32 does already).
The reason that the linker doesnt find libcurldll.a is that there is
simply the path to a proper "libcurl SDK" missing; if you have build
libcurl self then you can find this lib in the curl-7.x.y/lib folder.

Then I found a couple of issues with the makefile when used with such a
"libcurl SDK"; the original Makefile.m32 was designed to work with
source trees instead. I had no time to make it really nice now, but I've
hacked a bit around and made the Java binding compile and work with
recent libcurl SDK from the download page:
http://curl.haxx.se/gknw.net/7.29.0/dist-w32/curl-7.29.0-devel-mingw32.7z
in addition I created another libcurl SDK which uses the recently
introduced WinSSL instead of OpenSSL:
http://svwe10.itex.at/curl/curl-java/curl-7.29.0-winssl-sspi-spnego-zlib-devel-w32.7z
and here's a patched curl-java-0.2.3 package with hacked Makefile.m32
and a myset.[bat|sh] which shows you how to set the vars needed:
http://svwe10.itex.at/curl/curl-java/curl-java-0.2.3-p.7z

to compile simply extract the SDK and the java-curl package into a
common directory (.f.e. c:/projects) and then open either a CMD shell:
cd \projects\curl-java-0.2.3
myset.bat
mingw32-make -f Makefile.m32 [test]

or a MinGW bash shell:
. myset.sh
make -f Makefile.m32 [test]

If you choose to use your own libcurl and OpenSSL builds then you should
self copy together such a SDK which makes things way easier;
also for using OpenSSL you need to uncomment some lines in the makefile
(the OpenSSL Win32 lib names have changed from 0.9.8 to 1.0.x) depending
on if you want to link statically or if you want to use the static lib.

I have not yet fixed the trunk version since this one uses a Java
namespace, and I had problems to get this properly compiled - might be
this is related to the fact that I tried with an older JDK-1.5 ...

if you have still problems dont hesitate to ask!

HTH, Gün.
