Building in VC6, need unsigned long long

I need to build a purchased library (with source) that was built in VC 2010. We have to build with VC6. I ran across signed and unsigned "long long". I am using "_int64" for the signed type but was unable to find anything for the unsigned type. Has anyone run across a solution? Apologies if this is documented, I have had no luck in finding anything.

__int64 is a vendor-specific base type. It can be combined with the unsigned modifier, just like:

 unsigned char               unsigned __int8
 unsigned short              unsigned __int16
 unsigned int                unsigned __int32
 unsigned long               unsigned __int32
(unsigned long long)         unsigned __int64
                            (unsigned __int128)

Where the parenthesized names are not available in VC6, but are supported in the current version of Visual C++.
