IMAGE_FIRST_SECTION adds an integer representing a number of bytes to a pointer
of type IMAGE_OPTIONAL_HEADER* resulting in a change 240 times
(IMAGE_OPTIONAL_HEADER64*) or 224 times (IMAGE_OPTIONAL_HEADER32*) as large as
intended.

"SizeOfOptionalHeader: The size of the optional header, in bytes."

core.sys.windows.winnt.d:
---
PIMAGE_SECTION_HEADER IMAGE_FIRST_SECTION(PIMAGE_NT_HEADERS h) {
    return cast(PIMAGE_SECTION_HEADER)
        (&h.OptionalHeader + h.FileHeader.SizeOfOptionalHeader);
}
