GMP, Windows 98, Windows XP

[jojo 29]

Thanks Torbjorn Granlund, but if I use only Visual Studio C++ 6.0 and ".exe" 
files, executing times are similar too ? (I don't know how to manipulate 
".asm" files...)
So, using only VSC++ and exe files, is there a big difference ? You said no 
"because the bulk of the calculations are done in asm". But maybe threads 
are not managed on Windows 98 like on Windows XP? maybe the structure of 
Windows 98 is naturelly lower than the one of Windows XP... ?
