Hi again. Thanks a lot for your replies. I compiled using the Makefile.m32
file inside the lib folder using command "mingw32-make -f Makefile.m32" and
the Makefile at the root of the folder, with command "mingw32-make mingw32",
and the libraries and executable has built fine, with error 127 (which you
told me is no problem, its just when it builds the first time). Now I tried
to build the examples but this is the error it returns:

gcc -I. -I../.. -I../../include -I../../lib -I"../../openssl-0.9.8g/outinc"
./../zlib-1.2.3" -g -O2 -Wall -DCURL_STATICLIB -DUSE_SSLEAY
E_H -DHAVE_LIBZ -DHAVE_ZLIB_H -c 10-at-a-time.c
gcc -s -o 10-at-a-time.exe 10-at-a-time.o -L../../lib -lcurl
.8g/out -lssl -lcrypto -lgdi32 -L../../zlib-1.2.3 -lz -lwldap32 -lws2_32

C:\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot
d -lssl
collect2: ld returned 1 exit status
mingw32-make: *** [10-at-a-time.exe] Error 1
rm 10-at-a-time.o

I think that this is because the libraries are not install and the linker
did not find them (right?). So, what should I do? Sorry but I'm a complete
newby with this, so I kind of need some baby steps explanations hehe. Thanks
a lot!
