Libsigc++ compiles and runs under win32 (windows 95 and NT)
with the cygwin package available from Cygnus Solutions.
(http://sourceware.cygnus.com), Borland Builder 6 or Visual C++ 5.

Notes for egcs:
- A simlink is required from /bin/sh to $(CGYWIN_HOME)/bin/sh
  for configure to run.
- A bug in libtool results in compiling the dll stubs with the 
  wrong compiler which results in a minor error.  To fix
  this, a repaired version of ltdll.c is distributed.
- The dll fails to compile with libtool >1.2d  as a result of
  a bug in libtool.  A bug report of this is outstanding. 
  (use static libraries til fixed)


Notes for Microsoft Visual C++:

Microsoft Visual C++ does not provide partial specialization of
classes at this time which is a requirement for the regular
version of the library.  Also it requires the format of the
package to be different then that of the standard GNU package.
A special distribution is therefore required.

Two project files for building the library and its tests
are located under the win32 directory.  libsigc.dsp builds the
shared dll for the library.  wintest.dsp builds a simple
test that runs through all the libraries features.  

Unlike other platforms, VC++ does not support default
template arguments properly.  Thus the marshaller for
signals (normally hidden) must be explicitly specified.
The files distributed with .cc extension require modification.

(To compile from CVS which uses native Unix .cc extensions
you can use the instructions found on
http://depc14.gsi.de/hades/msdev-cc-ending.htm)

Exporting another library using libsigc++ can be 
fun because VC++ requires every symbol to appear
in the DLL that it uses.  This is a well known problem and
is documented in the Microsoft Knowledge Base.  The
instructions for exporting libsigc++ are basically the
same as those of STL class in Article #Q168958.
