Subject: [PATCH] MakeHeader: open files using binary mode

By default, open(sys.argv[1]) use Unicode mode.
The readlines() will try to convert with the default codec
(which depends on the i18n settings, so 'ascii' under
LC_ALL=C)

Open files using binary mode so no conversion will be done
by readlines(). But then, normal strings can't be used in
the rest of the code; either all strings have to be prefixed
with b'' or (simpler) the read line has to be converted to
a unicode string by calling decode() on it.
