binutils-gdb/bfd/pe-x86_64.c
Alan Modra d87bef3a7b Update year range in copyright notice of binutils files
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
