UINT32 is not a 64-bit safe type. Please use ULONG_PTR instead.

Yes, I don't want to copy the way a certain other organization implemented
its version. ;)

actually, this would be better written as:
((PIMAGE_SECTION_HEADER)(DWORD_PTR)((LPCBYTE)&((const 
IMAGE_NT_HEADERS*)(ntheader))->OptionalHeader + \
                           ((const 
IMAGE_NT_HEADERS*)(ntheader))->FileHeader.SizeOfOptionalHeader))

Hi Eric,

I'm not seeing too many LPCBYTEs in the code base, but I reckon const BYTE *
fits the bill. Why do you prefer DWORD_PTR over ULONG_PTR?

nothing against ULONG_PTR, more likely, my proposal only has one ugly 
ULONG_PTR cast, while they were two

I like your style! :)
