Compile-time issue in hrtimer.cpp on VC6

[Scott Maxwell]

Building the latest Crypto++ (from CVS) on VC++ 6 I now get:

C:\Source\SDK\CryptoPP5\hrtimer.cpp(66) : error C2520: conversion from 
unsigned __int64 to double not implemented, use signed __int64
C:\Source\SDK\CryptoPP5\hrtimer.cpp(66) : error C2520: conversion from 
unsigned __int64 to double not implemented, use signed __int64

Any ideas?

Thanks,
