I attached my logfile, so the patches gets not damaged 
because of wordwraps.

Building cURL & libcurl plus leakbug & libcomprex on Cygwin
with shared libraries using libtool and recent autotools.

So I did it now:
================
I installed the current release of libtool (builds OOTB)
and I have installed the latest autoconf and automake versions
that come with cygwin's netrelease plus all the other recent
devel stuff like binutils.

In the curl-src topdir I started:
I modified some files:

 # This flag accepts an argument of the form current[:revision[:age]]. So,

I run a bootstrap script:
=========================
#! /bin/sh

aclocal
autoheader
libtoolize --force --copy
automake --foreign --copy
autoconf

Then, as usual:
===============
./configure --prefix=/where/you/like/it 2>&1 | tee log.configure
make 2>&1 | tee log.make
make test 2>&1 | tee log.test
make install 2>&1 | tee log.install

Et voila, we get a shared libcurl:
==================================
$ ll

Now, to test it, I try to build a package which depends on it:
==============================================================
libcomprex is from here: http://www.gnupdate.org/

It seems to depend on some stuff from leakbug:
http://www.gnupdate.org/components/leakbug/index.xml
so I build this first:
======================
$ tar zxvf leakbug-0.1.3.tar.gz

Change here as well to get a .dll:

We only need one of 'configure.ac' or 'configure.in',
deleting the older one, as well the old 'missing' script:
=========================================================
$ rm configure.in 
$ rm missing

Run bootstrap:
==============
$ ./autogen.sh --prefix=/where/you/like/it

Make:
=====
$ make 2>&1 | tee log.make
$ make check 2>&1 | tee log.check
$ cp tests/.libs/leak1.exe libleakbug/.libs
$ cd libleakbug/.libs
$ ./leak1
int_ptr1 = 42
int_ptr2 = 10
str1 = Hello World!
str2 = Hello World!
Reallocating str1 to 15 bytes...
str1 = Hello World!!

Wow, that looks nice:-) Lets install it:
$ cd ../..
$ make install 2>&1 | tee log.install
$ cd ..

Now build libcomprex:
=====================
$ tar zxvf libcomprex-0.1.0.tar.gz

I changed here also a little bit:

$ cd libcomprex-0.1.0/

There are to configure templates, configure.in and configure.ac,
we don't need configure.in, so remove it:

$ rm configure.in 

There comes a 'bootstrap' script with this piece of software, it is
called 'autogen.sh'. Call this, there will be executed configure at
last step of the bootstrap. 

$ ./autogen.sh --prefix=/where/you/like/it

Now we are getting an error, I'm not sure about this, is it a bug
in libtool or what it is:
===
ltconfig: you must specify a host type if you use `--no-verify'
Try `ltconfig --help' for more information.
configure: error: libtool configure failed
===

Now remove '--no-verify' from configure (if you get this error too):

Run configure again:
====================
$ ./configure --prefix=/where/you/like/it 2>&1 | tee log.configure

Now it goes on.

$ make 2>&1 | tee log.make

$ make install 2>&1 | tee log.install

To make sure this is working right, type:
$ cd tests/.libs
$ ./decomprex ../file2.txt.gz

 Once upon a midnight dreary, while I
     pondered, weak and weary,
 Over many a quaint and curious volume
     of forgotten lore--
 While I nodded, nearly napping,
     suddenly there came a tapping,
 As of some one gently rapping, rapping
     at my chamber door.
 "'Tis some visitor," I muttered,
     "tapping at my chamber door--
     Only this and nothing more."

 Ah, distinctly I remember it was in the
     bleak December;
 And each separate dying ember wrought
     its ghost upon the floor.
 Eagerly I wished the morrow; --vainly I
     had sought to borrow
 From my books surcease of sorrow--
     sorrow for the lost Lenore--
 For the rare and radiant maiden whom
     the angels name Lenore--
     Nameless here for evermore.

 And the silken, sad, uncertain rustling
     of each purple curtain
 Thrilled me--filled me with fantastic
     terrors never felt before;
 So that now, to still the beating of my
     heart, I stood repeating
 "'Tis some visitor entreating entrance
     at my chamber door--
 Some late visitor entreating entrance 
     at my chamber door; --
     This it is and nothing more."



Done.
