clashes with boost::hash with windows visual c 8

[GoogleCodeExporter]

What steps will reproduce the problem?
1. include boost::hash headers
2. include sparsehash headers
3. use both
What is the expected output? What do you see instead?
no error messages.
boost::hash will complain that hash_compare is no part of boost, due to 
the fact that hash is called hash_compare in visual c++

What version of the product are you using? On what operating system?
microsoft visual c++ 8, windows xp

Please provide any additional information below.

Suggested fix:
Something similar to: 

put into each config.h 
#define SPARSEHASH_hash hash 

and into the windows config.h 

#define SPARSEHASH_hash hash_compare 

then replace in the remaining source and header files all calls to 
hash with SPARSEHASH_hash (as far as i've seen there are not many 
anyway) 

this will remove the generic #define hash and boost::hash will work 
just fine. 

#defines without program specific prefix naming is bad practice imho 
and there is no way to limit #defines to namespaces.

That's a good suggestion.  We'll do something like that for the next release.

This should be fixed in sparsehash 1.0.

While you provided the suggested SPARSEHASH_HASH define you still left the 
#define 
hash hash_compare in the sparseconfig.h for windows at line 35 and 36 in 
sparseconfig.h. This should not be necessary anymore and would still break the 
original compatibility problem of this issue. You might want to release a 1.01 
release without the #define

D'oh!  You're absolutely right.  Release 1.0.1 is coming soon...
