(It wasn't meant as patch that's why I put it between quotes.)
What do you mean with "what values IsWow64Process() returns" ? This is hardcoded
I've checked with a quick test that the return value and the PBOOL give the same
results on my Linux box (64-bit OS) as on my WinXP box (32-bit).
So I agree that the "patch" is not correct but it solves this issue (Skype
probably takes a different path on error).
