[Nel] Some more VC7 patches

[Vincent Caron]

I have another set of patches concerning NeL's and Snowballs VC7(.net) 
project files. It seems that my previous patch was not applied. Would 
you like an incremental patch or the full patch against the current 
public CVS ?

BTW, am I the only VC7 user on this ML ? My short experience shows no 
more caveat than VC6 for now.

PS: today's public has a buggy 'misc/stream.h', a copy/paste error while 
adding the multimap serialization support. I guess it's already fixed 
internally ...
