Summary: winddk.h: pack 1 for structures

Initial Comment:
Some structures in winddk.h requires "#pragma
pack(push,1)" and "#pragma pack(pop)" around
declarations. This is true at least for "struct _IRP"
(lines 975 - 1029 in winddk.h).

Are you still sure about _IRP?  I think the change of 
KIRQL to UCHAR may have fixed the allignmnent 
problem in _IRP.  If not can you point out where offsets 
differ?

Sorry, but I did not find a category for this bug.

In the line 130 of winddk.h (from Win32api-2.2.tar.gz), 
there is the following declaration:

typedef ULONG KIRQL, *PKIRQL;

This is not correct, and causes errors when you use
the IRP structure. So, when you use macros as:

IoGetCurrentIrpStackLocation(Irp)

you will get a bad pointer to the stack location, because
KIRQL is really CHAR type.  

The correct declaration is:

typedef UCHAR KIRQL;
typedef KIRQL *PKIRQL
