Visual C++ 7.1 patch for google-sparsehash ver. 0.6 about sparsehash HOT 3 CLOSED

In this version there is the possibility to test the impact of keys with larger
storage in time_hash_map. I have another version, where there is also a more
expensive comparison function. 
If you are interested, I can provide a patch.

I just made the 0.7 release, which incorporates some of the ideas of this 
patch: the
timing file uses more architecture-independent code, and it supports hashing
structures that are larger than int.

I've also added more windows support, particularly windows/config.h, which 
should
make it easier to use this code with vc++.

I still don't provide project files, but I hope that for 0.7, the patches 
necessary
for windows will be significantly smaller than they were for 0.6!  Let me know 
what
else I can do to make life easier for vc++ users.

I finally got my hands on Visual Studio myself, and feel comfortable making .sln
files part of the main distribution.  As of version 0.8, windows should be 
buildable
right out of the box.  Closing this patch.
