I have added few new targets to win32/Makefile.msvc:
       nmake check
       nmake check-keys
       nmake check-dsig
       nmake check-enc
             Run all ('check') or any particular xmlsec tests suite 
(cygwin or any other bash is
             required).
 
      nmake uninstall
             The opposite to 'nmake install'.

Unfortunately, none of the xmlsec tests succeed. For sigantures, the 
main problem
is that xmlsec-mscrypto does not support loading keys from pkcs12 files 
(do you think
it is possible to implement it?) The encryption just hangs on first test :(

I would appreciate if you can try these tests yourself. The test suite 
is the main "quality
control" mechanism in xmlsec and it would be really bad if 
xmlsec-mscrypto would not
be able to pass it :(

Also I have updated the examples/Makfile.w32 and added xmlsec-mscrypto 
to the list
of supported crypto libraries.
