• Delphi 2007 changed the implementation of CreateFmtHelp so that it clears the Win32 'last error'. Therefore, it was impossible to detect windows error in detection handler when EGpHugeFile help context was hcHFWindowsError. To circumvent the problem, all EGpHugeFile help contexts were changed to a negative value. HcHFWindowsError constant was removed. All Win32 API errors are passed in the HelpContext unchanged. IOW, if HelpContext > 0, it contains an Win32 API error code, otherwise it contains one of hcHF constants.
• Added method TGpHugeFile.GetTime and property TGpHugeFile.FileTime.
