To build avarice for Windows requires the use of Cygwin
<http://www.cygwin.com/> Specifically, this was built using the Previous
package of Cygwin. In the Cygwin installer, select the Prev radio button up
top when installing the packages. This should install cygwin 1.3.22-1, from
the Base tree in the Cygwin setup.

Get avarice from anonymous CVS as explained on the avarice project web
page. Then, in the avarice project directory:

    $ export $PREFIX=<your installation directory here>
    $ ./Bootstrap
    $ mkdir build
    $ cd build
    $ ../configure --prefix=$PREFIX
    $ make
    $ make install

If there are errors like: "undefined reference to `_htab_create_alloc'"
then re-install binutils (and not GCC) from Cygwin and re-run! This error
means that the libiberty functions that are needed in avarice need to come
from a binutils version of libiberty and not from a GCC version of libiberty.

This will create avarice.exe, which requires the following DLLs to execute:
- cygwin1.dll
- cygintl-2.dll
- cygiconv-2.dll

In Cygwin, you can check to see what, if any, DLLs are required of an 
executable by using the program cygcheck.exe that comes with Cygwin. For 
example if you cd to the $PREFIX/bin directory after building the project, 
and execute

    $ cygcheck ./avarice.exe

You should get something like (depending on your OS and it's installation 
location):

    .\avarice.exe
      .\cygwin1.dll
        C:\WINNT\System32\KERNEL32.dll
          C:\WINNT\System32\NTDLL.DLL
      .\cygintl-2.dll
        .\cygiconv-2.dll


If you want to build avarice with less DLL dependencies, then, in the avarice
project directory:

    $ export $PREFIX=<your installation directory here>
    $ ./Bootstrap
    $ mkdir build
    $ cd build
    $ ../configure --prefix=$PREFIX
    $ make LDFLAGS='-static' LIBS='-lbfd -liberty -lintl -liconv'
    $ make install
  
When you build avarice this way, you can verify what DLLs are required with
cygcheck in the $PREFIX/bin directory:

    $ cygcheck ./avarice.exe

    .\avarice.exe
      .\cygwin1.dll
        C:\WINNT\System32\KERNEL32.dll
C:\WINNT\System32\NTDLL.DLL
