Is this also true on Windows?
I've got a feeling that it's not because my program (ie main.exe + my own 
C++ DLL) runs on a plain WindowsXP installation that doesn't have anything 
else installed on it (apart from the Microsoft C runtime that comes as 
standard and which presumably doesn't contain GMP).

Thanks, Brian.
