I fixed some non-portable stuff I came across:
QueryPerformanceCounter
%I64d in printf format strings
Sleep
CheckDiskSpace
If there’s any other unportable stuff you know of I should fix, let me know.
I think I’ll move debug.log and db.log into the same directory as the data files (%appdata%\Bitcoin), rather than whatever the current directory happens to be.
