Hello, I updated to recent w32api-4.0.3 (22.9.2013) package and found a problem when recompiled my kernel driver under WinXP. It failed to load new driver. I compared what's different from old compile and found that there's a reference to ntoskrnl.dll instead of ntoskrnl.exe. What is ntoskrnl.dll? It's not present in WinXP, I only googled that some rootkits hide by this name, WTF? So I reverted to older version of libntoskrnl.a (1.4.2013), recompiled and it works again.
