Cpp doesn't build in 32 bits. How do I submit a bug report?

[Arkadiy Vertleyb (BLOOMBERG/ 120 PARK)]

Hi all,

I was able to successfully build in 64 bit MSVC, but 32 bit gives me an error.  
Apparently arrow uses some 64 bit stuff not supported by the 32 bit system.

How do I submit a bug report?

Thanks,
Arkadiy
