stub/amd64-win64.pe.h matches upx-v4.2.4
...
so that anti-virus checkers of apps for 64-bit Windows that are newly-
compressed by upx should not complain about new matches with malware.
This costs a few bytes and a small fraction of cycles in NRV2
de-compressors, but is considered to be a tolerable concession
to the cesspool environment of software for Microsoft Windows.
