[PATCH] Building SVN checkout fails with GCC.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Checkout current svn (r974)
2. Build with GCC (4.8.1) (or any other non MSVC compiler)

What is the expected output? What do you see instead?

The error was introduced by r898 zdenop@gmail.com ("fix VC++ build" ... by 
breaking non-VC++ builds ...).  The attached patch should fix it.

Linux build (gcc) should be fixed in r979.
svn r898 modified bbgrid.h and recent error was in hashfn.h. And the respective 
code in r898 bbgrid.h and r974 hashfn.h is different.
You can easily check that linux build works ok with r898 or r900 ;-)
