Hi,
 
Maybe you use some 3rd party library that has WIN32_WINNT >= 0x0501.   Anyway, find code in project that run it - MFC doesn't call it.

I usually set WINVER=0x0500 (and _WIN32_WINNT=0x0500), since I seldom use XP+ features.
 
Does this guarantee that the code runs on Windows 2000?
 
At work, in a large project, WINVER was set to 0x0500 - everywhere. I checked stdafx.h, Project Settings etc. Later, when we ran the executable on Windows 2000 SP4, we found out that a kernel32 function was missing: TzSpecificLocalTimeToSystemTime.
 
Looking through Winbase.h, it's clear that this function is indeed inside an #ifdef:
#if _WIN32_WINNT >= 0x0501
   ...
   TzSpecificLocalTimeToSystemTime
   ...
#endif // (_WIN32_WINNT >= 0x0501)
 
 
My question is: How is it possible that the compiler did not catch this? I guess an include-hell a la mfc + windows.h could yield this, but I really can't see where the error is. Have you seen anything like this?
