/*-----------------------------------------------------------------------------
This forward declares NT style structs, so you can declare uses of pointers
to them in headers without including the header that defines them, and without
referring to them as "struct _FOO*" but "PFOO" or "FOO*" instead.

The header that defines them should not use this macro, but stick to the
consistent style
typedef struct _FOO
{
    ..
} FOO, *PFOO;
typedef const FOO* PCFOO;
