--- Comment #1 from Reid Kleckner <rnk at google.com> ---
I don't believe this class is used anywhere for memory-mapped IO, so this isn't
a bug. The type was specifically widened to 32 bits in r217812 by David
Majnemer to add bigobj support, which allows reading and writing object files
with more than 2**16 sections.

The coff_file_header struct in llvm/include/llvm/Object/COFF.h is appropriate
for use with memory-mapped files.
