Doesn't compile on Windows & Visual Studio, missing ssize_t

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use MSVC 2010 to compile any file using btree.h

What is the expected output? What do you see instead?
Should compile, but fails because ssize_t is not known.


What version of the product are you using? On what operating system?
Windows 7 + MSVC 2010 (with matching SDK)

Please provide any additional information below.

Can be fixed by a patch to btree.h like:

#if defined(_MSC_VER)
#include <BaseTsd.h>
typedef SSIZE_T ssize_t;
#endif

This should work with MSVC versions >= 2010, older ones might not work anyway 
because of missing C++11 support.

Other issues remain, will open separate issues here for them.
